Follow-up.....I LOVE this solution! I have an album just for Canadian Quarters, and only for those from 1989-on (almost all of the ones I have are uncirculated). Here are some things to note, though.
Originally, I had those uncirculated quarters in A24 Direct Fit capsules, but they had too much rattle for my liking. And while I found I could get those capsules reopened, the whole process was a royal pain. Some were very hard to re-open.
So....if you are expecting to upgrade coins to higher grades on a regular basis, it will be a lot easier on you to use the cardboard/mylar 2x2's until you are sure that coin is not likely to be upgraded again.
As for the 5x6 coin holder pages, they are perfect for my needs. But since they are clear, and since I do not have complete pages most of the time, I am often looking down to pages below when there is an empty slot. One solution is to simply put blank white paper between each of the plastic holders. I am going to try to print the information for what ought to be there for all 30 spots in a mailmerge and insert that page under it's coin page so that I will have a description in every slot that does not have a coin.
