Des Moines, eastern Iowa and Sioux City
Most of Iowa's shops sell mainly sports cards, and many carry vintage too.
Des Moines, with Clive and Urbandale on its west side, has the largest group. The one that breaks the pattern is on East Euclid Avenue, in the Highland Park area north of downtown: a store that imports Japanese Pokémon and One Piece cards.
In eastern Iowa, Coralville and Davenport have sports-card specialists and Iowa City has a downtown comic shop. Sioux City, on the Missouri at Iowa's western edge, is served by a sports-card shop on Hamilton Boulevard.
Card shows, conventions, and tournaments happening across Iowa.
