Silver Calculator: Sterling, Coin & Fine
Sterling · coin silver · fine silver
Enter the weight and the fineness. This tells you what the silver inside is worth at today’s spot price — flatware, jewelry, scrap or bullion.
The fineness marks you will meet
- .925 — sterling. The usual standard for flatware, hollowware and jewelry. Often stamped
925,STERLINGorSTER. - .900 — coin silver. The old US coinage standard, and the mark on a lot of nineteenth-century American flatware.
- .999 — fine silver. Modern bullion bars and rounds.
- .958 — Britannia, and .800, common on continental European pieces.
Silver plate is not silver. EPNS, “silver on copper”, A1 and similar marks mean a microscopically thin layer over base metal. The recoverable silver is close to nothing regardless of how heavy the piece feels — refiners generally will not take it.
Weigh the silver, not the object
This is where estimates go wrong. A “sterling” candlestick is usually a thin silver shell filled with pitch or plaster and weighted with a steel rod; a knife with a sterling handle has a stainless blade cemented into it. Weighing the whole thing can overstate the silver several times over. Weigh what is actually silver, or expect the buyer to.
How the number is worked out
Weight is converted to grams with exact definitions, multiplied by the fineness, and priced against a live spot quote shown with its timestamp. If the quote is stale or the cross-check fails, no number is shown at all. The full set of guards is in the methodology.
What a buyer will offer
Less than melt, always — refining, assay and handling all cost money, and margins on silver are proportionally wider than on gold because the metal is worth less per gram. Antique or maker-marked silver frequently sells for well above melt to someone who wants the object rather than the metal, and melting it destroys that value for good.
Knowing the metal is worth $X is half the job; the other half is who pays closest to it. Where to sell silver coins goes through the dealers, the marketplaces and the auction houses, and shows where each one takes its cut — including the postal insurance rule that caps a lost bag of bullion at $15.
