Silver Coin Value Calculator
A one-ounce silver Britannia contains exactly one troy ounce of .999 fine silver. Older UK coins are valued by their silver content: pre-1920 coins are 92.5% silver (sterling), while coins dated 1920–1946 are 50% silver.
Use the presets for common coins, or weigh any coin and set the fineness manually. Collectible coins may be worth more than melt — this shows the metal floor value.
How it’s calculated: live spot price (GBP per troy ounce) ÷ 31.1035 × purity × weight. See our methodology for data sources and update frequency.
