1829/7 Capped Bust Half Dollar. O-101. Rarity-1. MS-62+ (PCGS).This is a very sharp example of the overdate variety, with the repunching of the date remarkably clear. A delicate patina of peach hues blankets each side, revealing hints of golden and violet iridescence at a tilt. The surfaces are overall smooth and free from distracting blemishes of any sort, rendering it decidedly choice at this grade level. The overdate variety is actually composed of two distinct die pairings, both utilizing a shared obverse die. O-101, as offered here, is slightly more common, while 0-102 is negligibly scarcer. A listing as a separate <em>Red Book</em> type ensures that both of these pairings see substantial demand from collectors.
