Nice coin VF condition, original toning, minimal contact marks, a few hairline scratches, as expected on a coin of this age.
In
mid-1807 the Draped Bust Half Dollar was succeeded by the Capped Bust
of Liberty that featured a reverse known to collectors whimsically as
the "sandwich board" eagle. Half
dollar die varieties from 1807-1836 are quite popular with variety
specialists. Since many of the design elements required to complete a
die were punched into it by hand, each die is readily distinguishable. In
Overton's system, the first die variety listed is given the number
101, and each date begins anew with this number, followed by O-102,
O-103, etc. Later die states within a single die pairing use suffix
letters. For example, 1808 variety 107 is identified successively as
O-107 and O-107a.
