Coin and Paper Money Collecting/twenty dollar bill



    i have a $20 bill that has GN (TWICE) onthe right side of the word twenty

Modern federal reserve notes (which is what you have) all have two letters to begin the serial number. The G signifies that it was issued for The Chicago Federal Reserve bank.  The N signifies that it was printed in Washington DC.  It certainly does not affect the value on a regular issue note.  You are not the first person to be thrown off by the two letter code.  We run a site about old money values and we see it all.  The first letter always has to do with federal reserve bank it was printed for and the second letter represents where the note was actually printed.

I can answer any question relating to valuing US Currency. My specialty is national currency, large-size currency, and small size issues between 1928 and 1957. Many bank notes have variables that can make two seemingly identical notes have very different values. That is why it is so important to work with an expert. I also work with rare Canadian banknotes as well as some foreign currency (mostly British Commonwealth countries). I have participated either as a buyer or seller in more than 500 different coin auctions.


I have been a full time currency dealer since 2006. I set up at about ten national coin and currency shows per year all across the country. My company has a retail location in Greenville, SC. I also run a website about old money values. I am also currently the director of currency auctions at Stacks Bowers. So I am in a unique position to see, value, and sell millions of dollars worth of paper money on a annual basis. I have been lucky enough to sell hundreds of individual banknotes worth over $10,000. I personally hold several world records for highest price paid for certain categories of banknotes. While I personally don't deal a tremendous amount of coins, I can provide sound advice on where to sell coins in NYC, and other major metro areas across the country. I have seen the worst of the worst and the best of the best when it comes to coin dealers.
