Any business that regularly buys used gold, silver, platinum or gems in Oklahoma needs a license from the Department of Consumer Credit for each location, backed by a bond and the applicant's fingerprints and photo. For every purchase the dealer records a description or photo of each item with any engraving (a weight and metal type alone is not enough), the amount paid, the date, and your name, address and driver's license number (or, if you have no driver's license, your date of birth and a general physical description), and you sign the record. The dealer keeps it for four years, open to the Department and police.
Used precious-metal items then stay at the licensed location, unaltered, for 10 days unless police release them sooner; the dealer may arrange a resale during that time as long as it keeps the item. Police who believe something is stolen can place a 30-day hold that can be renewed. Coins and bars made by a commercial mint are not covered by the act, and it sets no cash limit or check-only rule.
Pawnshops are licensed separately. When a pawnshop buys outright it must see a photo ID (or take a fingerprint), have you sign a declaration of ownership saying how long you have owned the item, report the purchase to local police within two days and hold it 10 days. Pawnshops may not buy from anyone under 18.
