Wisconsin regulates walk-in buyers under Wis. Stat. 134.71. Anyone in the business of buying secondhand jewelry needs a secondhand jewelry dealer license, silverware and flatware fall under the secondhand article dealer license, and pawnshops need a pawnbroker license from their municipality. Applicants are checked by local police for related convictions in the past ten years, and licenses run January 1 to December 31.
Before buying, the dealer must see an accepted ID, such as a Wisconsin or other state photo driver's license, a state ID card, a passport or a military ID; a government ID without a photo works only if the dealer takes your right index fingerprint. You complete and sign a state form in ink for each sale, the dealer keeps it at least a year and makes it available to police within 24 hours. A dealer may not buy from anyone under 18 unless a parent or guardian is there or has given written consent.
Jewelry and other secondhand items then stay with a jewelry or article dealer for 21 days and with a pawnbroker for 30 days, unaltered and open to police inspection; where a report must be filed electronically, the hold is 7 days after the report. Police can extend the hold on an item they believe was stolen. U.S. coins, any gold or silver coin and gold or silver bullion are exempt from the hold, and the statute sets no cash limit or check-only rule.
