The Division of Consumer Affairs found extensive fraud in the cash for gold business.

the urban crackdown resulted in nearly 10,000 citations for alleged, civil violations of State consumer protection laws at 71 jewelry stores, pawn shops, and other locations.  In addition, officers confiscated 35 scales that were of types not approved for cash-for-gold transactions, or were not registered with the Office of Weights and Measures.

“This Urban Cash-For-Gold task force covered northern, central, and southern New Jersey, to ensure all consumers are protected when they sell their jewelry,” Acting Attorney General John J. Hoffman said.  “The fact that our officers confiscated the scales used in nearly half of these stores demonstrates the great need to ensure these consumers are not cheated.”  http://www.njconsumeraffairs.gov/News/Pages/12182014.aspx
