Nutmeg Coin Posted April 10, 2013 Report Share Posted April 10, 2013 Unlike US coins where you just enter: Qty./Country /Coin Date/ Mintmark Denomination/Variety/Value, with the currency you need to enter serial number and Friedberg number; if you don't enter the Friedberg number, you will be charged a $5 research fee. This can be a little complicated because with some notes, such as the Bison note, there are numerous Friedberg numbers for the issue. Link to comment Share on other sites More sharing options...
