How many 1934 twenty dollar federal reserve notes are still in circulation?

Well, there are probably very very very few still in circulation. There are many obstacles an old dolalr bill has to survive in order to still be around today. One is that it must survive being circulated for 80 some-odd years! Unless it was sitting in a collection or a bank for that long, which means that the condition of it will probably be great! Also, it must survive the collector! When a lot of money collectors find an old bill in circulation, they usually pull it out and put it in their collection. The bill also has to survive the feds. annual buring of bills, because they just get to wrinkly and torn. Your best bet to find one is in a coin store, flea market, or the bank. I you choose to go to the bank in hopes of finding an old bill, go to a bank that's been around for quite a while for obvious reasons. Or, you could just hope one pops up when you shop! Hope this helped.
