1828 25/50C

The 1828 25 over 50 C quarter is not a new die blunder but the same corrected 1822 reverse die pulled from storage six years later and pressed back into service. Drawn from the combined 1828 mintage of roughly 102,000 pieces, this variety reuses the famous "50 C." denomination die that Mint workers had originally corrected in 1822 by punching a "2" over the "5" and a "5" over the "0." By the time it returned to the press in 1828, the die had developed rust marks across the fields, adding pitting that 1828 25/50C examples carry alongside the underdate. The reuse reflects how Philadelphia Mint engravers in the 1820s would economize on die production, keeping serviceable dies in storage rather than scrapping them, even when the dies carried obvious errors.

Authentication is straightforward under magnification: the lower curve of a "5" sits beneath the right side of the "25 C." denomination, and the "0" of the original "50" is visible behind and beneath the "C," typically as a complete circular outline. The variety is cataloged as Browning B-3, the specific die marriage pairing the original 1822 25/50C reverse die with a new 1828 obverse. Telltale die rust in the reverse fields, accumulated during the die's six years in storage, distinguishes 1828 25/50C examples from the earlier 1822 strikings. Specifications follow the Type 1 large-size format at 27 millimeters and 6.74 grams of 89.24 percent silver with a reeded edge. PCGS (Professional Coin Grading Service) and NGC (Numismatic Guaranty Company) attribute the variety on certified holders. Wear can obscure the underdigit on lower grades, so verification under a 10x loupe is essential before paying the variety premium.

Heritage Auctions and Stack's Bowers regularly handle attributed 1828 25/50C quarters, with values tracking the visibility of the underdenomination on the holder image. PCGS and NGC populations remain comfortably below 500 across all grades, with Mint State examples genuinely scarce above MS62. Variety collectors who already own the 1822 25/50C frequently pursue this 1828 companion to complete the denomination-blunder pair within the Capped Bust Quarter series history.
