Silver Certificates $1 Currency in Chicago, Illinois For Sale

In xxxx the United States discontinued the obligation to redeem holders of silver certificates to redemption in either silver coins or raw silver bullion, but the certificates remain as legitimate Federal Reserve currency. The certificates have a distinctive blue seal, except for Hawaii certificates, which have a brown seal.
All the certificates I have are in Above Average condition, although they are not formally graded. The corners are still sharp, the paper is still mostly crisp (but the Hawaii bills are a bit less crisp than the xxxx series), and the bills show very little wear of previous handling.
