Simple answer to a complex question, Use 2x2's ( or for larger coins 2.5x2.5's flips )in archival non PVC albums.
If you need to really look at the edge lettering/detail simply pull the coin out of the album and remove from the flip and view, Then fit in a new flip and put it back in the album.
Simple, easy and kind on your coins
