How to flip government surplus & police-seized jewelry
Jewelry lots can be real gold or a bag of costume pieces. They're sold as-is with no authentication, so the buyers who do well don't trust stamps. They value a lot by the precious metal they can verify and treat any stones as a bonus.
Who's actually selling jewelry on GovDeals
Jewelry is the single largest category on GovDeals, with about 1,600 live lots on October 31, 2026. Most of it isn't police-seized property, though. About 85% of those lots came from just 9 commercial sellers. Only about 140 came from government sellers, such as police departments and agencies clearing out unclaimed or forfeited property.
It also doesn't sell easily. From September 14 to October 31, 2026, only 20% of GovDeals jewelry auctions sold, one of the lowest rates of any large category (GovDeals statistics). Between August 2 and October 31, sold jewelry lots went for a median $125 with 5 bids. Many lots go unsold, so there's no need to chase one.
Legal to buy. The risk is value.
Unclaimed, forfeited and seized property is sold legally through government auctions, and you get clear ownership of what you win. The risk is that lots come with no appraisal, no authentication and no returns. The platform won't tell you what's real. That's your job before you bid.
Start from melt value. It's your floor.
Never trust a stamp
Plated and fake pieces get stamped "14K" too. Assume any mixed lot includes costume and plated items. If you can inspect before paying, a scale, an acid test and ideally an XRF analyzer or a jeweler will tell real from plated. If you can't inspect, bid only what the provable metal is worth after an honest discount, zoom in on every photo, and treat anything unclear as junk.
Where the resale money is
Where you sell depends on what you actually have:
- Verified, wearable pieces and watches: eBay and jewelry buyers. Price against eBay sold listings for comparable verified items.
- Scrap or broken gold and silver: a refiner or dealer, at melt value minus their margin.
- Coins and bullion: recognized spot or collector prices. Watch for replicas in mixed lots.
Red flags
- "Costume," "fashion," "unmarked" or "as pictured." Assume little or no precious metal.
- Photos too blurry to read stamps or check stones.
- A bid that only works if the "diamonds" are real. That's a gamble, not a flip.
- No weights listed on a lot you're valuing by melt. You'd be guessing at your floor.

Is police-seized jewelry safe and legal to buy?
Yes. Unclaimed, forfeited and seized property is sold legally through government auctions, and you get clear ownership of what you win. The risk is value: lots are sold as-is with no authentication. Note that most jewelry on GovDeals today comes from commercial sellers, not police departments.
How do you value a jewelry lot before bidding?
Start from melt value as your floor: estimate the karat and weight of the real metal and price it at the current spot price minus a refining discount. Count stones only when you can verify them, and treat anything you can't confirm as costume.
How do I avoid fake gold and diamonds?
Don't trust stamps, because plated and fake pieces are stamped too. Assume mixed lots contain costume pieces and price the lot so it profits on verifiable metal alone. If you can inspect, use a scale, an acid test, and ideally an XRF analyzer or a jeweler.
Where do you resell surplus jewelry?
Verified wearable pieces and watches sell best on eBay and to jewelry buyers. Scrap and broken gold and silver go to a refiner or dealer at melt value. Price against eBay sold listings for comparable verified pieces, and treat melt value as the floor.
