📊 Scrap Silver Calculator

Scrap silver is worth its pure-silver content at spot, minus the buyer’s margin. Fifty grams of sterling (.925) holds 46.25 grams pure, or 1.4870 troy ounces. At $31.50 spot the melt value is $46.84, and at an 80 percent payout you receive $37.47. This calculator runs that chain for any weight, fineness, and spot.

Silver’s low price per ounce makes margins brutal: the same 20 percent haircut that costs $93 on a gold chain costs $9 here, but the trip to the buyer costs the same. Batch silver before selling; single items rarely justify the errand.

How to Use This Calculator

Weigh the silver, pick its fineness, enter the spot price per troy ounce, and set the payout percent. The calculator returns pure content, melt value, and your payout.

The Scrap Silver Formula

Fineness is parts per thousand: sterling .925 is 92.5 percent pure. US 90 percent coin silver is .900 before wear; heavily worn coins lose a few percent to circulation. Flatware marked EPNS or “silverplate” is plated base metal with essentially no melt value.

Like gold, silver trades in troy ounces. A kitchen scale in grams is the practical tool; convert here. Beware buyers quoting per avoirdupois ounce, which inflates the divisor by 10 percent against you.

Worked Example

50 grams sterling, $31.50 spot, 80 percent payout. Pure = 50 x 0.925 = 46.25g. Troy oz = 46.25 / 31.1035 = 1.4870. Melt = 1.4870 x $31.50 = $46.84. Payout = $46.84 x 0.80 = $37.47. Buyer keeps $9.37.

Flatware set version: 800 grams of .800 continental silver. Pure = 640g = 20.5778 ozt. Melt at $31.50 = $648.20. At 80 percent = $518.56. Now the errand is worth it. Note: antique flatware sometimes beats melt as collectibles; check sold listings before scrapping anything with a maker’s mark. For gold items, our scrap gold calculator runs the parallel math.

Where Silver Sellers Lose Money

In the US, physical silver gains are taxed as collectibles up to 28 percent, same as gold. Keep purchase records or the entire proceeds may be treated as gain. And sell silver with gold when you can: refiners pay better blended percentages on mixed lots, and one assay covers everything.

A Short History of the Troy Ounce

The troy ounce comes from Troyes, the medieval Champagne fair town where merchants standardized weights for precious goods. Twelve troy ounces made a troy pound, unlike the sixteen of the everyday avoirdupois pound, which is why the systems diverged. The US Mint and every bullion market still price in troy ounces four centuries later: financial infrastructure outlives the fairs that built it.

The practical upshot is the one that costs sellers money: a “1 oz” silver round is 31.1 grams, while a kitchen scale’s ounce is 28.35 grams. Weighing troy goods on an avoirdupois scale overstates weight by nearly 10 percent, which is exactly the margin some shady buyers pocket. Know your ounces the way you know your karats; both are money.

Junk Silver Coins: A Special Case

Pre-1965 US 90 percent coins, “junk silver,” trade as a liquid commodity with tiny spreads: dealers buy and sell by face value multiples of spot. A $1,000 face-value bag holds about 715 troy ounces after wear, priced as a multiple like 22x face when spot is $31. It is the most efficient way to buy or sell small silver, with recognition no generic bar matches.

The catch is premiums and wear assumptions: bags trade below full melt to account for circulation loss, and retail premiums add 10 percent or more. For selling inherited coins, junk bags usually beat scrapping odd lots because the market is deep and standardized. Know the multiple, know the wear factor, and you will not be lowballed. Liquidity has value; junk silver proves it.

Silver Storage and Tarnish

Tarnish is surface chemistry, not value loss: silver sulfide darkens the surface while the metal beneath is untouched. Refiners do not care; they melt it. Collectors care somewhat; heavy polishing removes metal and can hurt numismatic value. For scrap purposes, sell it tarnished: cleaning wastes time and sometimes metal for zero extra payout.

Store silver dry and sealed: anti-tarnish strips in sealed bags slow the chemistry dramatically. The real storage question is security and insurance for larger holdings, not tarnish. And keep purchase records with the metal: basis documentation is what stands between you and a tax bill on the full proceeds. Boring paperwork, real money.
