Mike Cramer's first love was baseball cards. Before high school he had a mail-order trading card business. At age 30 he founded Pacific Trading Cards with money he made fishing crab in the Bering Sea. From 1980 to 2004, Pacific created more than 200 successful trading card products. In 2021, a Pacific Tom Brady rookie card sold for $117,000. Pacific's cards remain some of the hobby's most sought-after and other companies still emulate their innovations.
