The 1812/1 Half Dollar is one of several overdates in the Capped Bust Half Dollar series. Two 1812/1 overdates are known: one with a Large 8 and another with a Small 8. Both were created when leftover 1811 dies were overdated in 1812 instead of simply discarding the old dies. The 1812/1 Large 8 is considerably more rare than the Small 8, and the Small 8 commands a small premium over the regular 1812 type. Only one die pair (Overton 102) is known of the 1812/1 Small 8 variety.
In Mint State, the 1812/1 Small 8 is quite scarce. A handful of MS63 and MS64 examples are known. Only one Gem example is known.
