How do you remember who's on US paper money?

Answer 1

There really isn't a well-known mnemonic to associate each bill with its portrait, although conceivably anyone could create one for their own use. Mostly it's a matter of memorization - although of course if you have a bill in your hand you can just look at the caption below the portrait!

Bills in current circulation:

$1 - George Washington

$2 - Thomas Jefferson

$5 - Abraham Lincoln

$10 - Alexander Hamilton

$20 - Andrew Jackson

$50 - Ulysses S. Grant

$100 - Benjamin Franklin

No longer issued:

$500 - William McKinley

$1,000 - Grover Cleveland

$5,000 - James Madison

$10,000 - Salmon P. Chase

$100,000 - Woodrow Wilson (never used in general circulation, only for accounting purposes between branches of the government)

Regardless of rumors and internet myths, the US has NEVER issued any higher denominations. All much-ballyhooed "million dollar" bills are novelty items or outright fakes.
