Why Antique Dealers Choose Nu Stack
Sterling silver math, the right way
Trays, flatware, candlesticks — set the .925 purity, weigh, and Nu Stack returns the melt. Filtering Sheffield from sterling matters; Nu Stack helps you stop overpaying on silver-plate.
Gold-filled and rolled-gold awareness
Enter the real purity for gold-filled and rolled-gold-plate items with a purity override so they don't get logged as solid gold by mistake.

Inventory ledger that feeds the booth
Every metal piece tagged with cost basis and current melt. Pull a CSV when you re-tag prices for a fair next month.
Sellers CRM for repeat suppliers

Frequently Asked Questions
Does Nu Stack value antique jewelry beyond melt?
Nu Stack provides a melt floor only — the metal value before craftsmanship or provenance. Antique premium is dealer expertise; Nu Stack supplies the math underneath it.
Can I track silver flatware sets in Nu Stack?
Yes. Add the set as a single inventory entry with total weight and purity. Photo upload supported.
What about gold-filled or vermeil items?
Enter the effective purity with the purity override (for example, 1/20 12K gold-filled is about 2.5% gold by weight). Nu Stack computes melt from that rather than treating the whole piece as solid.
