1923-S

The 1923-S Walking Liberty half dollar arrived after a complete production gap in 1922, when no Walker was struck at any mint, and the resumption came only from San Francisco with 2,178,000 coins. While the mintage is not microscopic compared to the 1921 trio, the 1923-S earns its semi-key status from extreme strike difficulty and from a survivor population that skews heavily toward worn grades. The coin is widely regarded by specialists as tied for the hardest Walker to find with a genuinely full strike, a challenge that becomes the central problem when trying to complete a high-grade date set. Few issues in twentieth-century American coinage create the same gap between an MS63 example and a true MS65 with full design definition.

Strike characteristics on the 1923-S are notoriously soft on Liberty's left hand, the lines across her skirt, and the eagle's breast and leg feathers. Full Head and Full Body designations seen on other twentieth-century types do not have a direct Walker equivalent, but specialists watch for thumb separation on Liberty's hand and full feather definition on the eagle as the primary strike markers. Authentication should focus on the S mintmark punch style, which is the same upright serifed S used at San Francisco during the period, and on confirming weight at 12.50 grams and diameter at 30.61 mm. Reeded edge integrity should be checked for filing or seams that can indicate a cast or pieced fake. Original surfaces show satin to slightly frosty luster, and any unnaturally bright or overly reflective fields suggest a cleaning that grading services will body-bag. Die markers in the obverse field and on the reverse rock are documented in NGC Coin Explorer references.

Heritage Auctions and Stack's Bowers have brought 1923-S examples in MS65 and above into the twenty to forty thousand dollar range, with truly full-strike gems pushing higher. Professional Coin Grading Service (PCGS) reports limited population at MS66, and the Numismatic Guaranty Company (NGC) census follows a similar curve. Most collectors acquire the date in Very Fine to About Uncirculated and accept the strike compromise.
