Anyone in Tennessee who buys antique, used or scrap jewelry and precious metals to resell, melt or sell as scrap must register with the sheriff and chief of police in each city and county where they buy (Tenn. Code 38-1-201). For every purchase the buyer keeps a log in duplicate with a description of each piece (metal type, content and weight if marked, stones, serial numbers and other marks), your name, race, sex, height, weight, date of birth, address and the number from your driver license, state ID, passport, military ID or an accepted immigration document, and the date and amount paid. You and the buyer both sign it, along with your statement that you are the lawful owner, and a copy goes to the sheriff and police by noon the next day.
The buyer then cannot sell, trade, melt or alter the items for 20 days from the purchase, though it may keep them in a bank vault or other secure storage during that time. It cannot buy from anyone under 18 or anyone who appears intoxicated. Pawnshops follow the same rules when they buy jewelry outright, and their own law requires a 20 business day hold on other goods they buy. Breaking the Act is a Class A misdemeanor.
The Act does not apply to a business that deals only in coins, which is why a coin-only shop can buy and resell coins without the log or the hold. The Act sets no cash limit or check-only rule for these purchases.
