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.
