Still one dollar....sorry : (
If it is a normal one dollar bill it is worth one dollar only. If it is an antique bill which cannot be found in circulation now, you can auction it to antique bill collectors and they may buy it at a higher price...
$500.00
no because 20 dollars and one dollar are worth different money so that's why.
There was only one series of 1974 $20 bills so none of them would have a series letter. You may be looking at the Federal Reserve District letter instead. Please see the question "What is the value of a 1974 US 20 dollar bill?" for more information.
It's just one dollar.
One dollar.
Despite its age, a circulated 1974 U.S. $5 bill is only worth five dollars. A nice uncirculated one might retail for $7 to $8 or so.
One dollar.
All dollar bills have signatures printed on them; one is the Secretary of the Treasury, and the other is the U.S. Treasurer. An uncirculated series 1974 might sell for a few dollars, but it's not especially valuable.
it was on the 1 dollar bill
The Treasury does not put bar codes on bills. In any case bar codes weren't used in 1974. You may have a bill that was altered by somebody using a bar code printer.
