I guess I didn’t really answer your question. You asked how many. The answer is 37.
Why?
Where I work we get bills from as far back as 1932 and coins from even earlier. That’s all still in circulation, and at least once a month one of the younger cashiers will bring me a bill asking if it’s real or not. Yeah, it’s real - real old.
I should have included one more:
TWO DOLLAR BILL: Federal Reserve Notes with a small “FW” to indicate printed at the Fort Worth, Texas facility.
The total now stands at 38.
