Louisiana's secondhand dealer law (R.S. 37:1861 and following) covers anyone in the state who buys used jewelry, silverware, diamonds or precious metals as a business, and buying more than once a month counts. Each dealer needs a local occupational license and posts a bond with the city or parish, and a pawnshop license doubles as a secondhand dealer license, though pawnshops keep their records and report under the pawnbroker law (R.S. 37:1796 to 1798) instead of the secondhand dealer record and reporting rules (R.S. 37:1862.1). Before buying, the dealer records your name, address and the number of your driver's license (Louisiana or another state), passport, military ID or other government ID; with no ID the sale cannot go through. You also sign a statement that the items are yours or paid for. Records stay at the shop for three years, and a copy of each day's entries goes to the police chief or sheriff by noon the next day, sent electronically.
The dealer then keeps what it bought for 30 calendar days, on the premises or elsewhere in the same parish, before selling, melting or altering it, unless it can prove you had valid title. No dealer may buy gold, silver, jewelry or precious stones from anyone under 18, and shops may only be open from 7 a.m. to 7 p.m. (10 p.m. on Saturdays and in December).
Dealers in coins and currency are exempt from the whole law, and the photo and under-18 rules do not apply to manufactured bullion bars or coins at any dealer. The state's cash-payment limits cover copper and other scrap metals but expressly leave out precious metal objects, so state law does not stop a jewelry buyer paying cash. Temporary buyers who set up in a rented room or storefront are transient merchants under R.S. 37:1910, with their own daily reports and a 15-day hold.
