This is a U.S. $5.00  Silver Certificate. Series 1953A and is circulated. It has a blue seal on the front which distinguishes the silver certificate from other back notes. Different bank notes have different color seals. 

Silver certificate bills were printed in the United States from 1878 to 1964. They were legal tender dollar bills that were also redeemable in silver. They are distinguishable by the words “Silver Certificate” or a note about silver dollars “payable to the bearer on demand” printed on the front of the bill.

Please check scans for the condition of the silver certificates. Thanks for looking!
