$100 bill from 20s with red seal

[jnb1994]

So I owe my teller BIGTIME after what I got today (I'll explain next post). He had a $100 from the 20s (I think 23 if I remember right) with a red seal and asked me if it was worth anything. I wasn't sure but I owe him bigtime so if anyone has any knowledge about bills that would be great!

If it's a $100 note, it will be a 1966 or 1966A. All of these bills, even if well-circulated, carry a significant premium. A lower-grade '66 has a retail value of around $120. VF/XF bills are in the $150-$175 range and CU notes are around $200 with choice examples being worth multiple times that.

1966A bills are more sought after and are worth about 150% of a comparable 1966.

Small-sized $100 Notes (National Bank Notes) in 1929 had a brown seal. Red seals (Legal Tender Notes) were printed in 1966. The balance were green colored seals except for the gold seal on 1928 and 1934 Gold Certificates. If you can post a pic of the bill or tell us the issuing bank and/or who the signatories are, more information can be disclosed.

BTW, that is a reference to small-size notes only. If it's a large-size FRN with a red seal, it will be series of 1914. The red seal 1914 FRNs are considerably rarer than the blue seal variety. If this is the bill the teller has, it's worth $$$$.

It's also possible that the red seal could be mistaken for a brown seal, which would be series 1929. If it's a Federal Reserve Banknote, it carries a modest premium. If it's a National Banknote, the premium will depend on what bank it's from. Both types are marked "National Currency" in the upper border.
