Newport Beach-based Collectors Universe Inc. said Tuesday it wrapped up its buy of Certified Coin Exchange and a related business.
Collectors Universe, which values and authenticates coins, trading cards and other collectibles, said it paid $2.2 million for the company.
Certified Coin operates a subscription-based, dealer-to-dealer Internet market for certified coins.
In July, Collectors Universe paid $500,000 to buy the Coinfacts.com Inc. name, Web site and proprietary information about coins held by the company.
