Generic POS cannot price a Proof Set or an MS65 Morgan. SpotPro pulls Greysheet Bluebook, Grey Sheet bid, and CPG retail into buying, lookup, and inventory when you connect a Greysheet Dealer+ API key.
Where Greysheet appears
- NumisNexus — Guide context while you buy collectibles and slabs
- Coin Price Lookup — Staff reference screen: search the Greysheet catalog and see your suggested buy and sell margins
- Inventory edits — GSID-linked items show guide values on the item record
- Update Greysheet Products — One-click bulk repricing when the market moves, preserving your markups
Setup
Add API credentials once in POS Settings. Purchase presets can apply your buy discount rules on top of guide values — separate from whether you choose to apply premium adjustments to Bluebook in preset config.
