What is junk silver?
“Junk silver” is collector slang for circulated pre-1947 UK silver coins traded for melt content rather than numismatic value. Most are worn, damaged, or low-grade examples of common dates that carry no premium above silver content. Bulk bags of 500g, 1kg or 1oz of mixed silver coins are a popular way to buy silver at low premium over spot.
Why pre-1947?
UK circulating silver coins were sterling silver (.925) until 1919, then .500 silver from 1920-1946. From 1947 onwards, all UK circulating silver was replaced with cupronickel, zero silver content. So “pre-1947 UK silver” means anything in the .925 or .500 alloy era. See our pre-1947 vs post-1947 silver guide for the full breakdown.
Where this melt floor matters
Any pre-1947 UK silver coin will sell for at least its melt value, below that, no rational seller would let it go. The numismatic premium (rare date, key date, high grade, special design) sits on top. For circulated common-date pre-1947 silver, melt value is the floor and ceiling. For high-grade or scarce dates, melt is just the starting point.
