I received this email from my father in law. "old SILVER CERTIFICATE $1 bills and also $2 bills? I have a bunch of these in a box and would like to know if the SILVER CERTIFICATES were or are worth anything and also if the early $2 bills are more rare than the ones after the bicentennial are. We have pre bicentennial and post as well."
I know nothing about these as I focus more on coins. Any help is appreciated on where I can look to find more info. Thanks!
