Collector insights
- Design heritage: Percy Metcalfe is credited as the designer for the Pre Decimal 1939-1969 series. Designer attribution helps distinguish this issue from later restrikes or unofficial copies that reuse only the motif.
- Struck at: Royal Mint (Tower Hill), London, United Kingdom. Confirm the mintmark on your example before comparing prices — same-year issues from different mints often trade at very different levels.
- Mintage vs. survival: A moderate mintage of 1,680,000. Grade rarity is usually the driver of value here — mid-grade circulated pieces are common, but original-surface uncirculated coins can command a strong premium.
- Catalogue reference: Listed as
KM# 10, Sp# 6644. Use this reference code when cross-checking auction archives, dealer inventories, and standard printed catalogues.
