8. You might think that it would be easy to make a phony dollar bill. Many people have tried, but they haven't been very good at it. There are some good reasons for this. First of all, the pictures on American bills are in the shape of an oval; so if you see a one-dollar bill with the picture of George Washington in a circle, you can be certain that it's not a real bill. Check the eyes on the picture, too. The eyes on the picture of a real bill are sharp and clear; so there's another sign to watch for.
   9. Some people say that a bank teller can spot a counterfeit bill just by feeling it. If there is reason to believe that a bill is not real, there are other signs to us, though. It takes a close look, but if you check the treasury seal, you'll see that the points on a counterfeit are not quite sharp enough. The serial numbers are a third giveaway. The type use by the United States government cannot be purchased anywhere else. Since they're difficult to copy, the serial number should tip off a counterfeit bill.
   10. Perhaps the most interesting part of the real bill is the border. The pattern of thin lines is made by a very special machine. The design of thin lines is so complicated that it's almost impossible to match them. Those who try usually pause some of the lines to run into each other, or else some of them blur or blot.
   11. Now that you know some of the signs of a counterfeit bill, what about the pictures? Thomas Jefferson is on the two-dollar bill, and Abraham Lincoln is shown on the five. If you're not sure of a ten-dollar bill, check the picture of Alexander Hamilton. For a twenty, you should look for the picture of Andrew Jackson, and on a fifty-dollar bill, you'll see a picture of Ulysses Grant. You see, we're like the Greeks and Romans when we put pictures of famous men on our money, too. Actually, it would be ridiculous to expect a counterfeiter to put the wrong picture on a bill.
   12. Have you ever seen a counterfeit coin? If a coin feels greasy, that's one of the first signs that it's not real. You can probably hear a fake coin just by dropping it on a hard surface. A counterfeit will sound dull, while a real coin will have a definite ring to it.
   13. You don't need to look for trouble ail the time, but if you have reason to think a coin or bill is a counterfeit, perhaps some of these tips will help you out.
