I had a problem with some of my larger coins and sent away for some self adheisive flips to fit them in.
However when they arrived they were too big to put in my 2x2 album.
this is how I overcame the problem
this is the oversize flip next to a normal 2x2

I overlaid the 2x2 over the big one and marked out the square.

I then put the coin in the flip.

Finished 2x2 and fits perfectly in my album
