I recently purchased 3 of the Whitman Coin Folders so I can sort out which coins I do and don't have.

Is there some trick to getting the coins into their slots or is it just me having problems? I was trying to put my quarters into their appropriate slots last night and could only get 25% to go in correctly and completely, the rest stick out above the edge, like they shouldnt (and thats after trying to push them in all the way)

Thanks
