Our 14th collectable, commemorative Husker coin recognizes the tradition of the Blackshirts that turned 50 in 2013. 2" diameter, this keepsake will be sure to spark conversations about all the outstanding players the Huskers have had on defense who were awarded a Blackshirt - a tradition that was started 50 years ago when an assistant coach walked into a local sporting goods store to pick out a different colored jersey for the defensive team - and the clerk made him a deal on black shirts. A unique start to an outstanding tradition. Makes a great gift!
