The different values of money are called "denominations." You can tell what denomination a coin is by its size, its color, and of course by what it says on it. Paper money is a little trickier, because it's all the same size and color. Reading the bill will tell you what it's worth…but there's another way too. Each denomination of paper money has a portrait of a famous American on it: George Washington $1 - One Dollar Abraham Lincoln $5 - Five Dollars Alexander Hamilton $10 - Ten Dollars Andrew Jackson $20 - Twenty Dollars Ulysses S. Grant $50 - Fifty Dollars Benjamin Franklin $100 - One Hundred Dollars
