Notes:
The 1846 "Overdate" Quarter Eagle is an interesting variety that still puzzles researchers.  Clearly, all of the numbers in the date were re-punched into the die but was this done to correct the positioning of the date or was it done to "re-date" the die?  Is the final digit a 6 over another 6, a 6 over a 4 (as some experts have suggested), or a 6 over some other number (1846/5 $10 Gold Pieces from the New Orleans Mint are known to exist)?  Either way, this is a very elusive and popular variety.

PCGS does not recognize this variety.
