Live spot. Melt value on every coin. AI coin ID. Deal scoring. Built so the counter can work out a buy price faster than the customer can second-guess it.
Always free to use. Every new account unlocks all Pro features for 2 weeks — no credit card required.
Eagles, Maples, Krugs, sovereigns, AGE/ASE fractionals — Nu Stack shows what you paid, melt at live spot, and a typical premium estimate for each coin type (not a live dealer quote).
Photograph a customer's coin and get its identity, metal content, and melt value in seconds.
SMA, RSI and MACD computed from gold and silver price history, in Market Updates. Indicators, not predictions.
Group scrap and broken jewelry into a refinery lot in Sell / Ship and record the settlement when the wire hits.
