Introduction:The American Government states that about 1% of the paper money is fake or counterfeit. That is very small because the government goes to great lengths in investigating counterfeit cases. The government has also made it increasingly harder to counterfeit money with the increasing complex design of the dollar bill.
First start to feel the currency. If you work with money a lot (cashiers, business owners, etc,.) than they can pretty much tell the difference between a real one and fake one simply by the touch. If you are not that experienced you still have some idea of how a dollar bill should feel. The ink on the bill rises off the paper. You can definitely feel the ink on a real bill.
If you are still unsure of the legality of the bill, you can compare it with another of the same amount (a $1 to a $1, $50 to a $50, etc.). Also, it may be best to compare with another of the same year because the government has changed the design a few times ever since the 90's.
Look at the borders of the bill. Real currency has very fine, clear and clean borders, Fake bills may have pictures that are very blurry, dull and flat. There is quite a lot of detail in a real bill.
Check the colored strands. They should have small blue and red fibers within it. They should be within the bill rather than being placed or printed on it.
Always check the watermark. It is probably one of the more simple ways to check if the money is fake or not. Simply hold it up to the light and see. The watermark matches the printed mark.
