Anyone in South Carolina who buys gold, silver, platinum or gemstones from the public to make a profit is a dealer under S.C. Code Title 40, Chapter 54, and that includes items taken in pawn. Each dealer needs a yearly permit from the local police chief or county law enforcement agency, granted after a background investigation, and may operate only from a fixed premises: not from a vehicle, flea market, hotel room, home or short sublease. The state law replaces any city or county rules on the business.
At every purchase the dealer writes down the date, the amount paid, your name, sex, race, age and address, and your driver's license number, plus each item's size, weight, pattern, engraving and any unusual marks, and gets your signature. Without a driver's license you can use another photo ID with an identifying number, such as a DMV photo ID, a passport, a military photo ID or a South Carolina photo voter card; with no ID at all, the dealer cannot buy. The book is kept three years and is open to police, who may share your identity only with other law enforcement, prosecutors or a court.
Everything except coins must stay at the shop, or in the county of purchase, for 21 days without being resold, melted or altered. Dealers may not buy from a minor unless a parent or guardian with ID is present. A dealer who knowingly buys stolen metal owes the owner three times its fair market value, and willful violations are misdemeanors that bar a repeat offender from holding a permit for at least two years, or at least five after a third conviction.
