WASHINGTON — The Supreme Court won't consider the constitutionality of an Ohio law that bars precious metals dealers from advertising without a license.

The justices on Monday declined to take up an appeal from Liberty Coins, a gold and silver dealer that claims the law violates the free speech rights of businesses.

Ohio officials say the 1996 law was enacted to protect consumers from theft and help police track down stolen wedding rings, gold bracelets and other items resold at stores that buy gold and silver merchandise.

A federal judge in 2012 ruled the law unconstitutional because the state failed to prove the license requirement was effective in curbing theft, fraud and terrorism. But the 6th U.S. Circuit Court of Appeals reversed that ruling last year.
