Nice Peace dollar! Does it have an S mint mark on the back? The '24 S is a better date coin, worth more than the '24. Either way, you can't beat a silver dollar for a buck! Congrats.
I'm pretty sure she was a brand new teller, looked quite young. I'd never seen her there before... granted, I hardly ever go there, but still. When I asked the older guy who is head teller if they had large dollars, he says no, and she responds "I just got a few in today!" and he looked a little surprised. So I'm thinking he had no idea about them.
I'm always asking for halves and big dollars in hope of scoring a peace, morgan, or ASE. I can't imagine anyone giving them to me, but I keep asking just in case. I do get the occaisional ike, but I haven't got a 40% ike yet. Nice score. What are the other coins in your hand? Ikes?
