This stamp says Champion Discs on the inside and usually (I think) has the words "The Choice of Champions for Disc Golf" below the Bar. There is another stamp that is similar, but it is older and has square edges. You can see that on on the Valkyrie. Let's call this one Champion Bar. Simply and descriptive
