it's a bicentennial bill with the stamp of the day and cancelled the day it was printed.
April 13, 1976. I have several with a postage stamp affixed and cancelled with the postmark (date).
Two-dollar bills are generally worth two dollars. Adding a postage stamp to it wouldn't affect the value if the bill. The stamp itself, if rare, might be worth more than two dollars.
These have a retail value (like at a coin show) of about $3 to $4.
Its worth about $2.
Bill Gates should be on an postage stamp.
2 Dollars
It's worth $2.01.
The wording should be "INdivisible", but in any case it's something that was added separately after the bill was printed. In that case it has no added value, because the separate stamp makes it a damaged bill.
1934 ten dollar bill green with B stamp
Good question and not one that there is a good answer to. The only value I can think off would be to be able to prove that the bill was obtained on a specific date, as evidenced by the postmark. And since the US Post Office does not apply postmarks to currency, the stamp was put on so that they would postmark it. The bill would be devalued by the stamp and ink in the minds of most currency collectors.
The series 1976 two dollar bill does not have enough age to it to be a collectible item. Although amounts can change, currently a 1976 two dollar bill is worth approximately four dollars in uncirculated condition.
There were many of these notes taken to the post office to get a stamp and a first day cancel seal -- they are not rare. In a nice holder, it has a retail value of $3 to $4.
