Over 40 Years of Excellence

Stamp Services in North America is a division of Unicover Corporation, founded in 1968 by Wyoming native James A. Helzer. Located next to the majestic Rocky Mountains in historic Cheyenne, Wyoming, Unicover became a printer, a manufacturer and a global marketer of some of the most prized coin and stamp commemoratives in the world.

In the North American market, we’ve represented the postal administrations of 24 different nations, bringing the joys of stamp collecting to hundreds of thousands of collectors. In 1981, Unicover became the first American company ever to sign an agreement with the People’s Republic of China.

Today, we offer New Issue Services for Australia, China, France, Germany, Great Britain, Hong Kong, Israel, the Republic of the Marshall Islands and Sweden.
