1831

The 1831 Capped Bust Half Dollar carries a mintage of 5,873,660 pieces, placing it among the highest-production years of John Reich's lettered-edge design. By this point in the series, half dollars had become the dominant silver workhorse of American commerce, with banks using bagged halves for interbank settlement rather than releasing them widely into retail circulation. That banking pattern explains why a meaningful share of 1831 halves survived in higher grades despite the enormous original mintage, since coins stored in bank vaults faced less wear than typical pocket pieces. Overton catalogs approximately 26 die marriages for the year, ranging from common Overton-101 through scarcer combinations that draw active interest from die-marriage specialists.

Every 1831 half was struck on a 13.48 gram planchet of 89.24 percent silver, measuring 32.5 millimeters across, with the edge inscription FIFTY CENTS OR HALF A DOLLAR applied by the Castaing machine before the obverse and reverse were impressed. Authentication for the year focuses less on a single date or letter punch and more on the specific die marriage, with diagnostics including star position relative to the cap, leaf-tip placement on the reverse wreath, and the spacing of the date numerals. The Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) both routinely apply Overton attribution to 1831 holders when the die marriage is identifiable, and Heritage Auctions consistently breaks out die marriages in its catalog descriptions for premium examples.

For type collectors, 1831 offers one of the most cost-effective routes to a sharp Capped Bust half dollar, with abundant supply in Very Fine through About Uncirculated grades. Mint State examples are likewise available enough that registry collectors can be selective about luster, strike, and surface quality. Die-marriage collectors will find the 1831 a rewarding study year because of the marriage count and the wide range of survival rates within it. Background on John Reich's design progression is available in the Capped Bust Half Dollar series history.
