Collector insights
- Design heritage: Arnold Machin (obverse), Richard Guyatt (reverse) 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: Royal Mint, Llantrisant. Confirm the mintmark on your example before comparing prices — same-year issues from different mints often trade at very different levels.
- Low mintage: Only 83,672 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 (.925) — 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
