I have this 1923 $1 silver certificate. I'm pretty sure that's a fold error on it, but my knowledge about paper currency is very limited so I was hoping you guys could let me know what you think, and what you know about these error bills. Thanks!

Interesting. Not tape? It's condition, I would think, makes its value, if any, small but what do I know? Good luck. Cool.

I have that dollar. Mine has been graded by NGC there currency department. Got a good grade. I don't know about that one. I agree with Longstrider!
