Under RSA Chapter 322, a city or town may license dealers in old or scrap metals and second-hand articles (everything except furniture and books), and the license names the one place the business may operate. For each purchase the dealer records a description of the goods, the date and time, and your name and residence, verified with a government-issued photo ID. Police may inspect the shop, its stock and its books, and a dealer licensed for old metals must send the police chief a record of a transaction, with a copy of your ID and a photo of the metal, when the chief asks, and keep those records for 2 years.
State law sets no holding period for gold, silver or jewelry; the 10-day hold and company-check payment rule in RSA 322:16 apply only to catalytic converters. Each licensing board can add its own rules and conditions to the license, so a hold or reporting schedule at a particular shop usually comes from the town. Dealers may not buy from anyone under 16 without written consent from a parent or guardian.
Pawnbrokers fall under RSA Chapter 398, which covers loans on pledged goods rather than outright purchases. No one may take anything in pawn from a minor or a visibly intoxicated person. Pawnbroker licensing is in force only in cities of more than 40,000 people and in cities and towns that adopt it; there, licensed pawnbrokers record pledges with a government photo ID and keep them on the premises for at least 4 months unless redeemed.
