Florida regulates walk-in gold and jewelry buyers as secondhand dealers under Part I of chapter 538. Each dealer registers with the Department of Revenue, submitting fingerprints for a background check, and displays the registration at the shop. At every purchase the dealer fills out a transaction form with your name, address, workplace, phone numbers, date of birth and physical description, your right thumbprint, digital photos of the items, and the type and number of the government photo ID you show. You sign a statement that you own the goods or are entitled to sell them. The record goes to the sheriff or police chief within 24 hours, and the dealer keeps a copy for 3 years. Knowingly giving false ownership information or a false ID and taking payment is a felony.
Gold, silver and platinum items, gemstones and jewelry must stay at the registered location for 30 calendar days before the dealer may sell, melt or alter them, and police with probable cause can order a 90 day hold. Dealers may not buy from anyone under 18, from someone visibly intoxicated, or from anyone using a name other than their own, and they may not trade between 10 p.m. and 8 a.m. or through a drive-through window. Coins and assayed bullion marked with weight and fineness are not "secondhand goods" under the law, so these record and hold rules do not reach a coin or marked-bar sale, and dental materials are left out of the definition of precious metals.
Selling outright to a Florida pawnbroker falls under the Florida Pawnbroking Act (chapter 539) instead: the pawnshop is licensed by the Department of Agriculture and Consumer Services, records your ID and thumbprint on a transaction form, holds what it buys unaltered for 30 calendar days, and may not buy from anyone under 18.
