WSC Sports is a Wisconsin sports memorabilia retailer established in 1984. With locations in Waukesha, Brookfield, Appleton, and Greendale, the company serves collectors and fans seeking merchandise connected to Wisconsin teams and sports more broadly. It offers autographed and unsigned collectibles, including jerseys, footballs, baseballs, bats, helmets, mini helmets, photographs, trading cards, bobbleheads, and other memorabilia. Shoppers can browse by sport, team, or category, with selections covering football, baseball, basketball, collegiate athletics, and entertainment. Featured team collections include the Green Bay Packers, Milwaukee Brewers, Milwaukee Bucks, and Wisconsin Badgers.

WSC Sports also hosts athlete autograph signings and promotes an extensive selection of signed items that it says are certified authentic. For higher-value signings, the company says representatives from Fanatics, Beckett, or PSA may be present to authenticate items. Additional services include custom framing to display and preserve memorabilia, as well as a fundraising program that supplies curated merchandise at a discount, with organizations keeping the difference from sales and owing nothing for unsold items.
