I Have A 1928 $2.00 Bill In Mint Condition... How Much Is It Worth?

Take it to several different coin collectors, and see what they say, you don't want to sell it to the first offer if they make one. You might even call the museum and talk to them about it. Hope this helps, good luck to you. Remember me in your will? Lol

Depending upon what the potential buyer will consider mint, you could probably get a maximum of around $40 and a minimum of $10-$15.

It could be worth it anywhere from $ 5.00 dollars to $ 150.00 dollars.

The value depends on various attributes.  I have one worth $30.00.  You must take it to a reliable
appraiser or coin dealer and even then you can't be sure of its value.  I have had trade dollars and Morgan dollars called counterfeit but were not, so you can't trust anyone.

The most honest dealer I know of is Littleton Coins in New Hampshire.

Not much help, but just a few thoughts.
