5 Pounds - Elizabeth II Decimalisation, Silver proof

Issued to mark the fiftieth anniversary of the United Kingdom's decimalization on 15 February 1971 — Decimal Day — this piece commemorates the conversion that replaced the centuries-old pounds, shillings, and pence system with units of 100 new pence. Jersey, as a Crown dependency, conducted its own parallel decimalization rather than adopting Westminster's legislation directly, issuing its own decimal coinage under separate authority from the same date.

The selective gold plating on this proof is applied to specific design elements rather than the full field — a technique common to Royal Mint contract work of this period.
