Meet Our Leadership Team

Maynard Sundman (1915-2009)


Maynard Sundman turned his passion for collecting into a successful mail-order business with a novel approach to advertising. Instead of hobby publications, he focused on comic books, Sunday newspaper supplements and general-interest magazines. In the booming post-WWII consumer era, his strategy worked. Under his leadership, company growth necessitated moves to ever larger locations. Today, Littleton Coin Company occupies a 20-acre campus and generates an estimated $50 million annually.
