Design details

Collector insights

• Design heritage: James Barton Longacre 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 2 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.
• Gold issue: Gold (.900) (.100 copper) — bullion demand competes with numismatic demand. Weight and fineness (not just face value) drive the melt-value floor.
• Catalogue reference: Listed as KM# 73, PCGS# 7501-7503, 7505-7527, etc.. Use this reference code when cross-checking auction archives, dealer inventories, and standard printed catalogues.
