Design details

Collector insights

• Design heritage: Christian Gobrecht is credited as the designer for the Standard circulation coins series. Designer attribution helps distinguish this issue from later restrikes or unofficial copies that reuse only the motif.
• Struck at: United States Mint of Philadelphia. Confirm the mintmark on your example before comparing prices — same-year issues from different mints often trade at very different levels.
• Low mintage: Only 960 pieces reported. This puts the issue into key-date territory for its series; expect steep grade-based price scaling and a higher counterfeit risk — provenance and third-party grading matter.
• Precious metal content: Silver (.900) (.100 copper) — bullion value provides a price floor, and many circulated examples were melted during the 1979–1980 and post-2010 silver spikes, reducing the surviving population.
• Catalogue reference: Listed as KM# 100, PCGS# 6959-6973, 7015-7021. Use this reference code when cross-checking auction archives, dealer inventories, and standard printed catalogues.
