Treasure Hunter – Gold & Silver Deal Scanner

Melt-value deal badges for gold and silver listings on Facebook Marketplace, Craigslist, Whatnot and eBay. Free daily badges.

Treasure Hunter puts a melt-value badge on gold and silver listings while you browse Facebook Marketplace, Facebook groups, Craigslist, Whatnot and eBay. For each listing it reads the title and price on the page, works out the karat or silver purity and the weight, and shows: • the metal and purity (10K, 14K, 18K, .925 sterling, .999 fine and more) • the weight it found and the melt value at today's spot price • a deal rating — STRONG, GOOD, MODERATE or NEGOTIATE — and a suggested top offer • warnings for plated, gold-filled or "simulated" items, and listings with no weight Open a listing and you get a detail panel with the full melt breakdown. A hands-free voice calculator ("14 karat, 10 grams") gives melt value anywhere on those sites, and you can save the Facebook groups you buy from. FREE: deal badges on 10 listings a day, no account needed. UNLIMITED: sign in with a Nu Stack Pro or Business account (or a Nu Stack free trial) for badges on every listing. Plans are at nustack.app. How it works and privacy: • Listings are scored on your computer. Listing content is never sent to Nu Stack or anyone else. • The extension only runs on the marketplace sites above. • It fetches live gold and silver spot prices from Nu Stack, and if you sign in, checks your plan. • No ads, no tracking, no data sold. Melt values are estimates from the listing text and live spot prices. Always check the item, its weight and purity before you buy. Not financial advice. Treasure Hunter is made by Nu Stack (nustack.app) and is not affiliated with Facebook, Craigslist, Whatnot or eBay.
