I use the following:

· SIZE 2 ½” X 2 ½”(A) WITH 1 ¾” CROWN SIZE HOLE for silver eagles, silver rounds, crowns, etc.

· SIZE 2 ½” X 2 ½”(B) WITH LARGER 2” SIZE HOLE !

The 2" hole on the 2.5" flip is used for bacarrat/oversized chips. Fits pretty nice. Then the cardboard is standard at 2.5x2.5. I have them in boxes so its easy to manipulate. I had them in plastic pages but they became cumbersome for a number of reasons.
