Nu Stack scores every chain, ring, and silver tray in seconds. Don't pay flea-market prices on a kilogram of 14K.
Always free to use. Every new account unlocks all Pro features for 2 weeks — no credit card required.
Weigh a tray of sterling, set the purity to .925, and Nu Stack returns the total melt in seconds. Ideal for estate-sale lots priced as a single unit.
Snap photos of the unfamiliar coins. Nu Stack returns mint, year, composition, and ballpark value — fast enough to negotiate before someone else does.
Stack 12 chains and a watch into one entry. Nu Stack averages purity, totals melt, and grades the asking price.
Generate signed PDFs documenting what you bought and what you paid. Useful for the seller, the lawyer, and your own records.
After buying, open a Google Maps search for nearby coin dealers, pawn shops, and gold buyers in one tap — turn intake into outflow the same day.
Nu Stack calculates melt value — the floor under any precious metals piece. Antique craftsmanship and gemstone value are appraisal categories Nu Stack does not cover.
Use Coin ID on each coin, save it to your portfolio, then see the totals on the Coin Portfolio view. For lots of 50+, Bulk Import (Stacker plan and up) accepts a CSV if you've already cataloged elsewhere.
Yes. It's a calculator. Whether you disclose your buying methodology to the seller is your choice and depends on local rules.
