Silver-plated items (marked EPNS, “silver plate” or “Sheffield”) contain almost no silver, and only solid silver counts. Weigh items without stones or non-silver parts.

What each result means
- Pure silver content = [Sterling (.925) weight]×0.925 + [Coin silver (.900) weight]×0.9 + [Fine silver (.999) weight]×0.999 + [.800 silver weight]×0.8
- Melt value = [Pure silver content]÷31.1034768×[Silver price per troy ounce]
- Expected offer = [Melt value]×[Buyer’s payout]÷100
Example values
How the main result changes when Sterling changes and everything else stays at the example values above:
| Sterling (.925) weight (grams) | Expected offer |
|---|---|
| 100 | 169.76 |
| 150 | 226.86 |
| 200 | 283.96 |
| 250 | 341.06 |
| 300 | 398.15 |
| 400 | 512.35 |
Formula
Pure silver = Σ weight × purity
Value = pure silver (troy oz) × spot price; offer = value × payout %
Worked example
Inputs: Sterling (.925) weight: 200 grams; Coin silver (.900) weight: 50 grams; Fine silver (.999) weight: 0 grams; .800 silver weight: 0 grams; Silver price per troy ounce: $48; Buyer's payout: 80 %.
Results: Pure silver content = 230 g; Melt value = $354.94; Expected offer = $283.96.
Frequently asked questions
How do I value scrap silver?
Pure silver weight × the spot price.
Is silver plate worth anything?
Very little. The silver layer is extremely thin.
How do I test silver?
Look for hallmarks (925, sterling); a magnet test rules out steel.
