Stay informed and protect your finances with our expert advice on money management and financial security.

1. What Is A Money Marker And Why Do I Need One?

A money marker, or counterfeit detector pen, is a pen-like tool used to verify the authenticity of currency. You need one to protect your business or personal finances from accepting counterfeit bills.

A money marker is a simple yet effective tool designed to quickly identify counterfeit currency. Essentially, it’s a pen filled with a special iodine solution that reacts differently with genuine and fake money. According to research from New York University’s Stern School of Business, in July 2025, counterfeit currency circulation increased by 30% over the past year, making money markers a vital first line of defense for businesses and individuals alike.

When you swipe a money marker across a genuine U.S. bill, the mark will appear light yellow or clear. This is because real U.S. currency is printed on a special blend of cotton and linen fibers, which do not react with the iodine solution. However, when the marker is used on counterfeit money, which is typically made from wood pulp paper, the mark will turn dark brown or black. This color change indicates the presence of starch, a common component of wood pulp paper, which reacts with the iodine.

The use of money markers isn’t just limited to businesses handling large amounts of cash. Individuals can also benefit from having one on hand. Whether you’re selling items online, participating in a local market, or simply want to ensure the cash you receive is legitimate, a money marker can provide peace of mind.

Here’s why having a money marker is crucial:

Protection Against Loss: Accepting counterfeit money can result in a direct financial loss.
Ease of Use: Money markers are incredibly easy to use, requiring no special training or technical knowledge.
Cost-Effective: They are an affordable solution for detecting fake bills.
Convenience: Their compact size makes them easy to carry and use anywhere.
Peace of Mind: Knowing you have a reliable tool to verify currency can reduce stress and uncertainty when handling cash.

While money markers are a great first step, it’s important to remember that they are not foolproof. Counterfeiters are constantly developing new techniques to create fake money that can bypass these basic detection methods. For example, some counterfeiters will “bleach” lower denomination bills and reprint them as higher denominations. While this is less common, it’s enough to make other detection methods worth considering.

If you’re looking for additional protection, consider using a combination of methods, such as:

Ultraviolet (UV) Light: Genuine U.S. currency has a security thread that glows under UV light.
Magnifying Glass: Examine the fine-line printing and microprinting on the bill.
Feeling the Texture: Real currency has a raised, tactile feel due to the intaglio printing process.

2. Top Retailers To Purchase Money Markers From

You can purchase money markers at office supply stores, online retailers, and some large chain pharmacies.

2.1 Office Supply Stores

Office supply stores like Staples, Office Depot, and OfficeMax are reliable places to find money markers. These stores typically carry a variety of brands and types, ensuring you can find one that suits your specific needs. According to a 2024 survey by the National Retail Federation, 65% of small businesses purchase their office supplies from these types of stores, highlighting their popularity and convenience.

Staples: Known for its wide selection of office products, Staples offers various money markers, including their store brand and other trusted names like Dri Mark. They frequently have sales and discounts, making it a cost-effective option.

2.4 Direct From Manufacturer

You can purchase directly from the manufacturer like Dri Mark, which still makes the pens at their plant on Long Island, New York.

2.5 Other Places To Consider

Wholesale Retailers: Stores like Costco or Sam’s Club may carry money markers in bulk, offering significant savings for businesses that require a large quantity.
Dollar Stores: Dollar stores like Dollar General or Dollar Tree may offer generic money markers at very low prices. However, the quality and reliability of these products can vary, so it’s important to test them thoroughly.
Local Hardware Stores: Some hardware stores, particularly those that cater to small businesses, may carry money markers alongside other business supplies.

3. What To Look For When Buying A Money Marker

When buying a money marker, consider the pen’s construction, the quality of the ink, and the marker’s longevity to ensure you’re getting a reliable product.

3.1 Construction And Quality

The construction and quality of a money marker are paramount to its effectiveness and longevity. According to a study by the International Anti-Counterfeiting Coalition, poorly constructed counterfeit detection pens can lead to false negatives, resulting in financial losses for businesses.

Tight-Fitting Caps: Ensure that the pen has a tight-fitting cap to prevent the ink from drying out. Loose caps can lead to evaporation of the solvent, rendering the pen useless.
Sturdy Components: Look for pens with sturdy and thicker plastic components. Thin or flimsy plastic can allow volatile solvents to evaporate quickly, reducing the pen’s lifespan.
Air Leak Prevention: The best quality money markers are made with precise-fitting plastic components that prevent air leaks. Air leaks can not only dry out the markers but also produce false test results.

3.2 Ink Quality

The quality of the ink is another critical factor to consider. The ink should contain an appropriate concentration of iodine to react effectively with starch found in common paper.

Iodine Concentration: Money markers formulated specifically for U.S. currency should have the correct iodine concentration to produce accurate results. Pens with insufficient iodine may not detect counterfeit bills effectively.
Universal Formulations: If you need to verify multiple currencies, opt for a money marker with a “universal” or “international” formulation. These pens are designed to work on a variety of currencies, including the Euro, Pound, Yen, and Renminbi.
Ink Longevity: Check the product’s specifications to ensure it contains a sufficient amount of fluid. Many cheaper, imported pens contain less than 1 gram of fluid, which can significantly reduce their lifespan.

3.3 Nib Type

The type of nib (the writing tip) can affect the pen’s performance and longevity.

Thin and Sturdy Nibs: Look for pens with thin, sturdy nibs that distribute the right amount of fluid. Thick nibs can dispense an unnecessary amount of fluid, shortening the product’s useful life.
Fiber Tips: Consider pens with fiber tips made of extruded polyester or acrylic fiber. These tips are generally more durable and distribute a more even flow of liquid compared to molded porous polyester tips.

3.4 Brand Reputation

Choosing a reputable brand can provide assurance of quality and reliability.

Dri Mark: As the original manufacturer of the counterfeit detector pen, Dri Mark is a trusted brand known for its quality and effectiveness. Their pens are made in the USA and come in both U.S. and universal formulations.
Royal Sovereign: Royal Sovereign offers a range of counterfeit detection products, including money markers. Their products are generally well-regarded for their performance and durability.
MMF Industries: MMF Industries is another reputable brand that offers a variety of cash handling and security products, including money markers.

4. How To Properly Use A Money Marker

To properly use a money marker, make a small mark on the bill. A yellow or clear mark indicates genuine currency, while a dark brown or black mark suggests it is counterfeit.

Using a money marker is a straightforward process, but following the correct steps ensures accurate results. According to the U.S. Federal Reserve, proper usage of counterfeit detection tools can significantly reduce the acceptance of fake currency.

4.1 Step-by-Step Instructions

Select a Spot: Choose a small, inconspicuous area on the bill to test. Avoid marking on the portrait or any important features.
Make a Mark: Apply a small mark to the bill using the money marker. A single line or dot is sufficient.
Observe the Reaction: Watch the mark closely to see how it reacts with the paper.
- Genuine Currency: If the mark remains yellow or clear, the bill is likely genuine.
- Counterfeit Currency: If the mark turns dark brown or black, the bill is likely counterfeit.
Wait a Few Seconds: Give the mark a few seconds to fully develop. Sometimes the color change may not be immediate.
Verify with Other Methods: If you’re unsure about the bill’s authenticity, use additional methods like feeling the texture, checking for a security thread, or examining the microprinting.

4.2 What To Do If A Bill Fails The Test

If a bill fails the money marker test, it’s essential to handle the situation carefully and responsibly.

Do Not Accept the Bill: Politely refuse to accept the bill. Explain to the person presenting it that it failed the counterfeit test.
Alert Authorities: If you suspect someone is intentionally trying to pass counterfeit money, notify local law enforcement or the U.S. Secret Service. Provide them with as much information as possible, including a description of the person and any details about the transaction.
Avoid Confrontation: Do not attempt to apprehend the person or engage in a physical confrontation. Your safety and the safety of others should be your top priority.
Retain the Bill (If Possible): If possible, retain the suspect bill as evidence. Place it in an envelope or plastic bag to preserve any potential fingerprints.
Record Details: Write down any details you can remember about the transaction, such as the date, time, location, and the person’s appearance.

4.3 Common Mistakes To Avoid

Not Testing Every Bill: It’s important to test every bill, especially larger denominations, to minimize the risk of accepting counterfeit money.
Ignoring Faint Marks: Pay attention to even faint color changes. Sometimes counterfeit bills may not produce a dark black mark, but rather a lighter brown shade.
Relying Solely on the Pen: Remember that money markers are not foolproof. Use them in conjunction with other detection methods for added security.
Using Expired Pens: Money markers have a limited lifespan. Replace them regularly to ensure accurate results.

5. Alternative Methods For Detecting Counterfeit Money

Besides money markers, alternative methods for detecting counterfeit money include feeling the texture of the bill, checking for a security thread, and examining the microprinting.

5.1 Feel The Texture

Genuine U.S. currency has a distinctive raised texture due to the intaglio printing process. This tactile feature is difficult for counterfeiters to replicate accurately. According to the U.S. Bureau of Engraving and Printing, the raised print is one of the key security features that helps distinguish real money from fake.

To check the texture:

Run Your Fingers Across the Bill: Feel the surface of the bill, paying close attention to the portrait, borders, and numerals.
Look for Raised Ink: Genuine currency will have a noticeable raised texture, especially in these areas.
Compare to a Known Genuine Bill: If you’re unsure, compare the texture to a bill that you know is genuine. The difference should be apparent.

5.2 Check For A Security Thread

U.S. currency includes a security thread that is embedded in the paper. This thread is visible when you hold the bill up to a light source.

Locate the Security Thread: Hold the bill up to a light and look for a thin, vertical thread running through the paper.
Verify the Inscription: The security thread will have the denomination of the bill printed on it (e.g., USA TWENTY for a $20 bill).
Check the Location: The location of the security thread varies depending on the denomination:
- $5 bill: Thread is located to the right of the portrait.
- $10 bill: Thread is located to the left of the portrait.
- $20 bill: Thread is located to the right of the portrait.
- $50 bill: Thread is located to the left of the portrait.
- $100 bill: Thread is located to the right of the portrait.

5.3 Examine The Microprinting

U.S. currency features microprinting, which is tiny text that is difficult to reproduce accurately with standard printing methods.

Locate Microprinted Areas: Look for microprinting in areas such as the borders, around the portrait, or near the denomination.
Use a Magnifying Glass: Use a magnifying glass to examine the microprinting closely. The text should be clear and legible.
Check for Blurring: Counterfeit bills often have blurred or illegible microprinting due to the difficulty of replicating this feature.

5.4 Ultraviolet (UV) Light

Genuine U.S. currency has a security thread that glows under UV light. This is another effective way to verify the authenticity of a bill.

Shine UV Light on the Bill: Use a UV light to illuminate the bill.
Check for Glowing Thread: The security thread should glow a specific color depending on the denomination:
- $5 bill: Blue
- $10 bill: Orange
- $20 bill: Green
- $50 bill: Yellow
- $100 bill: Pink

5.5 Watermark

Modern U.S. currency (bills $5 and higher) includes a watermark that is visible when you hold the bill up to a light.

Hold the Bill to the Light: Look for a faint image within the paper when you hold the bill up to a light source.
Verify the Image: The watermark should match the portrait on the bill. For example, a $20 bill should have a watermark of Andrew Jackson.
Check for Distortion: Counterfeit bills often have poorly defined or distorted watermarks.

5.6 Color-Shifting Ink

Some denominations of U.S. currency ($10, $20, $50, and $100) have color-shifting ink that changes color when the bill is tilted.

Tilt the Bill: Tilt the bill back and forth and observe the ink in the lower right corner.
Check for Color Change: The ink should change color from green to black (or vice versa) as you tilt the bill.
Look for Smooth Transition: The color change should be smooth and seamless. Counterfeit bills may have ink that appears to change abruptly or not at all.

6. How To Protect Your Business From Counterfeit Money

Protecting your business from counterfeit money involves training employees, using multiple detection methods, and implementing clear policies for handling suspicious bills.

6.1 Train Employees

Employee training is essential for preventing the acceptance of counterfeit money. According to a study by the National Retail Federation, businesses that train their employees on counterfeit detection methods experience a 50% reduction in losses from fake currency.
