Hawaii Brown Seal $20 Notes:
Twenty dollar Hawaii notes can either be from the series of 1934 or 1934A.  Both are fairly common in circulated conditions.  All Hawaii $20s have a serial number that starts with L.  If the serial number on your Hawaii $20 ends with a star then it will command a nice premium.

Most brown seal twenty dollar bills are worth less than $100.  There are plenty of exceptions based on the condition and serial number of each note.  Send us an email admin@oldcurrencyvalues.com with a picture of the front and back of your brown seal $20 bill.  We can check it for varieties and make an offer.
