Indiana regulates most walk-in buyers of used jewelry and other used gold, silver and platinum as precious metal dealers under IC 24-4-19. A dealer may buy only at a permanent place of business it owns or leases for at least 12 months, and must register every year with the Secretary of State and with the city police or county sheriff for each location. Mint-issued coins and ingots are excluded from the definition of precious metal, so coin and bullion sales fall outside these rules.
For each purchase the dealer checks and copies your government photo ID, photographs the item and writes a bill of sale in duplicate that you sign, listing your name, address, date of birth and driver's license or Social Security number, the price and a description of each piece. You get the second copy. The dealer keeps the records at least two years and reports each day's purchases to the local police or sheriff. No dealer may buy from anyone under 18.
Each piece then stays at the shop where it was bought for at least 10 calendar days, kept separate and unaltered, and open to police inspection. Pawnshops follow the same 10-day hold under the pawnbroking law and also take your signature and right thumbprint on the bill of sale. The precious metal dealer law sets no cash limit or check-only rule, and a knowing or intentional violation by a dealer is a Class A misdemeanor.
Established retail jewelers are handled differently. IC 24-4-13 covers a jeweler located in a commercially zoned area, open to the public, primarily selling jewelry and remitting at least ten thousand dollars a year in Indiana sales tax on jewelry sales. When one of these jewelers buys used jewelry, you sign a bill of sale in duplicate listing the date, price, a description of each piece, your address and date of birth, and the type, issuing agency and number of your government ID; you keep the second copy. The jeweler keeps its records at least two years, shows them to police on request and may not buy from anyone under 18. That law has no registration, daily report or holding period, and a violation is a Class A misdemeanor. Trade-ins toward new jewelry are exempt.
