1828 O-107 R2, Curl Base Knob 2, Capped Bust Half Dollar

Obverse: 4
Reverse: F (Third Marriage)
O-107 R2 is below, O-107a R7? is at bottom
This is the second marriage for this Type, being more common than the O-106. Though readily available, there is a higher demand, especially since the O-106 is borderline rare. The late die state with a crack through the second 8 in the date is extremely rare. Examples survive problem free in all grades to MS66. This marriage sometimes will command a premium, especially for eye appealing specimens.

PCGS Graded AU55. A truly crusty original from the Mike King collection. Has some "chunks" at the rim below the date to really give it some character. Bowers notes: Deeply toned in charcoal-gray and, on the obverse only, steel-gray patination. There are no outwardly distracting abrasions, and the surfaces actually present as remarkably smooth for having seen light circulation. A sharply defined representative of this scarce die pairing.

And a couple of shots focusing on the area below the date. These clumps appear to be metal, on top of the milling, and there also appears to be a die line or crack at the tip of the curled base of 2.
