I have 1939 Nickles and on the front of the holder they are in it says 1939-BU. Can you tell me what "BU" means? Thanks, Chop
Usually it means brilliant uncirculated (roughly MS60/61) Sometimes some tricky individuals use it to mean borderline uncirculated, like AU55 or AU58. Your's is probably the first one.
BU is sort of a dated term, it means Brilliant Uncirculated. It would equate to MS (Mint State) on the 70 point scale.
