Before you sell here

  1. 1

    Know your metal floor before you walk in.

    Gold is — and silver — an ounce right now. Our offer checker compares an offer with metal value and dated examples of published buy prices.

  2. 2

    Know New York's seller rules.

    New York has no single statewide rulebook for coin shops that buy from the public. The rules come from city, county, town and village laws, plus state law for pawnbrokers (General Business Law Article 5).

    No statewide holding period for coin or bullion dealers was found.

    Source: NYC DCWP Inspection Checklist: Secondhand Dealers (ID, signature, records, LeadsOnline, 15-day rule, minors, scales), NYC Administrative Code 20-264 to 20-268 (definitions, license, fee, restrictions: minors, 15-day hold) · All New York rules

  3. 3

    Call ahead for anything bigger than a few coins.

    Ask whether the person who prices collections is in that day, and whether they pay by cash or check for larger amounts.

Questions to ask Nassau Diamond Buyers

We couldn't confirm these from public sources, so ask before you go:

  • What would you pay today for a 1 oz American Silver Eagle, and for $1 face value of pre-1965 silver? (Ask two shops the same question to compare.)
  • Is an appraisal free, or free only if I sell to you? Do you put it in writing?
  • How do you pay for larger amounts — cash, check or wire — and is there a cash limit?
