How to Quickly Evaluate Silver at an Estate Sale
Silver is one of the most consistently mispriced categories at estate sales. Sterling silver gets sold as silverplate; silverplate gets priced as sterling; coin silver flatware sits in dollar bins. A 10-minute investment in learning silver identification reliably pays off every time you encounter a tray of miscellaneous flatware or a drawer of serving pieces. The tests are simple, the marks are consistent, and the difference in value is significant.
The Hallmark System: What to Look For
Turn over every piece and examine the back. Sterling silver in the US is marked 'Sterling' or '925.' British sterling uses a lion passant (walking lion) plus additional assay marks. German silver is marked '800' or '835' (lower purity). 'EPNS' (electroplated nickel silver), 'silver plate,' 'Sheffield plate,' or no mark at all indicates plating over base metal, not solid silver. The mark is the single fastest sorting tool available.
Weight as a Quick Filter
Sterling silver is significantly heavier than silverplate for equivalent pieces. Pick up a fork or serving spoon and compare it to a known sterling piece — the weight difference is noticeable. A sterling tablespoon weighs approximately 40–55 grams; a silverplate equivalent weighs 20–30 grams. This isn't definitive, but it's a useful first filter when marks aren't immediately visible.
The Magnet Test
Silver is non-magnetic. If a piece is attracted to a magnet, the base metal contains iron or nickel, indicating silverplate or silver-filled construction rather than sterling. This test doesn't positively confirm sterling — non-magnetic doesn't automatically mean silver — but it quickly eliminates plated pieces made on steel bases. Keep a small magnet in your kit.
Coin Silver: The Overlooked Category
American coin silver (marked '900,' 'Coin,' or 'Pure Coin') was made from melted coins, typically from the late 18th to mid-19th century. It's lower purity than sterling (90% vs. 92.5%) but often of significant age and craftsmanship. Coin silver spoons and serving pieces are frequently undervalued at estate sales because buyers focus only on 'Sterling' markings. Pieces marked 'Coin' or with early maker's stamps are worth researching.
Calculating Melt Value as a Floor
Sterling silver has a melt value based on current spot price. As of mid-2025, sterling silver spot is approximately $28–$32 per troy ounce. A sterling tablespoon at 40 grams = 1.29 troy ounces × 0.925 (sterling purity) = ~1.19 troy ounces of silver × spot price = approximately $33–$38 in melt value alone. Collector or pattern premium adds on top. Melt value is your floor — don't pay more than 50–60% of melt value for silverplate.
Popular Patterns and Their Premium
Certain sterling silver flatware patterns carry significant collector premiums beyond melt value. Tiffany patterns (Chrysanthemum, English King, Vine), Gorham patterns (Chantilly, Strasbourg), and Wallace patterns (Grand Baroque, Sir Christopher) are actively collected and sell for 2–5x melt value in complete sets. A full 8-place setting of Gorham Chantilly in excellent condition is worth $800–$2,000 versus approximately $300–$400 in melt value.
