I put the majority of my collection in Whitman folders. I'm having trouble with a few Canadian coin types.
First off, the last 'cents' folder (1989-up) doesn't have enough holes to finish the set, as in the end they were making magnetic and non-magnetic versions of the penny.
My nickel folder's last hole was for 2012.
The dime folder is OK; lots of room left.
My last quarter folder is #5 (2001-up). It actually ends with some of the 2008 quarters listed. The Mint has released 29 circulated quarters since the last hole in that folder, and is planning at least 5 more issues in 2014 (Arctic and Caribou). I'm going to get another Whitman #3 folder and re-label it for now, but has anyone heard of when (if) a #6 folder will be printed? (I tried using a generic U.S. quarter coin book but the Canadian quarters just fall out)
