1827 Square Base 2 Half, Fine 15
Very Rare Overton-137 Die Marriage

1827 50C Square Base 2, O-137, Low R.6, Fine 15 PCGS. Bust half dollar collectors know that the 1827 has the most die marriages of any date, and many attempt to collect them all. A complete set requires 49 varieties, excluding Overton-listed subvarieties. Of those varieties, O-137 is third-rarest, trailing only O-149 and O-148. The identifier for O-137 is described by Dr. Glenn Peterson as "three or four die marks to the right of the right wing resembling extra feathers protruding into the field beneath the RI in AMERICA." They are evident, though faded, on the present lavender-gray representative. Although well circulated, the surfaces are uncommonly free from abrasions aside from a slight rim knock at 5:30 on the reverse.
