Will,
We use the 2 1/2 x 2 1/2 cardboard & mylar holders, in 12 pocket pages and haven't had a problem. I buy both at a local shop for coin collectors.

For appearances, I don't staple the holders, I use white rectangular tabs ("labels") to hold them shut....I place the fold on the left and use a tab at the top and the bottom. I leave the right side open so the chip can be slipped in and out ( not only do we like to look...we like to touch, too!! ) About once a year I go through the binders and add TCR numbers to any that need it. At the same time, I spot check for bleeding, sticking, etc. Been doing it this way for ?5-6? years with no problem.

Here's a few of our chips...love the Las Vegas Club one armed bandit! A classic Lady Luck with the Nevada mold....Love the dieswirl mold on the Horseshoe 25¢...the Golden Slot Club was an old downtown casino, the building looked like a giant slot machine!!
