Dumb question from a noob here...I bought a box of 11 strikes at a garage sale last weekend for $70. I recently became interested in collecting them after winning a few last year in Las Vegas, and happened to stumble on these. They're all pretty common from what I can see, but it was a fun find.

Anyway, I notice that some have large capsules, and others have capsules barely larger than the strike. Are either the large or small capsules replacements? Or do different casinos issue them with these varying capsule sizes?

Any help would be appreciated. Thanks!
