The $100 bill is one of the most widely circulated and targeted denominations for counterfeiters. With the advancements in printing technology, counterfeit bills have become increasingly sophisticated, making it challenging for the average person to distinguish between a real and a fake $100 bill. However, there is a simple and effective method to verify the authenticity of a $100 bill using a marker. In this article, we will delve into the details of this method and provide a comprehensive guide on how to use it.
Introduction to the Marker Method
The marker method involves using a special type of pen or marker that can detect the presence of starch in paper. Real US currency is made from a blend of 75% cotton and 25% linen, which does not contain starch. On the other hand, most counterfeit bills are printed on regular paper that contains starch. When the marker is applied to a real $100 bill, it will not leave a mark or change color. However, if the bill is counterfeit, the marker will leave a black or colored mark, indicating the presence of starch.
Understanding the Science Behind the Marker Method
The marker method is based on a chemical reaction between the ink in the marker and the starch present in the paper. The ink in the marker contains a substance called iodine, which reacts with starch to produce a dark blue or black color. When the marker is applied to a real $100 bill, the iodine in the ink does not react with the cotton and linen fibers, resulting in no change in color. However, if the bill is counterfeit and contains starch, the iodine will react with the starch, producing a dark blue or black mark.
Types of Markers Used for Verifying Authenticity
There are several types of markers available on the market that can be used to verify the authenticity of a $100 bill. Some of the most common types of markers include:
The most popular type of marker is the Counterfeit Detector Pen, which is specifically designed to detect the presence of starch in paper. This pen is widely used by businesses and individuals to verify the authenticity of US currency.
