Who's knowledgeable about U.S. Silver Certificates -- $1 bills?
I have 25 Silver Certificates with consecutive numbers. New / Crisp / Uncirculated.
Series 1957 -- over 50 years old.

Is there a guidebook on U.S. currency prices out there? Would like to get a value on this group of bills.
I assume there would be a premium in value for 25 with consecutive numbers (vs. 25 with random numbers)?

Not looking to sell. Just need a prox. value, or what guide to use.
Thanks.
