Direct fit Air-Tite holders are designed to fit the most popular coin sizes without the need of that foam ring.  I have now sourced and stocked all sizes for coins I cut.  I actually recommend them now with my more delicate cuts.  These coin capsules turn your cut into an casino chip style, air tite, damage free token...great for your pocket, the golf coarse, and even the poker table.  Also great for re-assembly and showing around of my Numismatic Jigsaw Puzzles.
