Mike,

I know your question was on storages cases but this is what I did on a frame...

I had the same problem when I wanted to frame my hard rock collection. I was not happy to be hiding one side of the chips.

Picture takes awhile to load but you can see what I did.

Parts List:

Matte:
======
16"x20" (63 chips) $15.95 - Emerald Green from http://www.cassidyframes.com/parts/parts.html shipping was free in month of Jan 2002

Acrylic Sheet:
==============
16"x20" $7.95 ea. ("filters out 45% of Ultraviolet rays"...) - I tested this with my blacklight and the reflection back on the security markers is fainter when done with the Acrylic sheet over the chips instead of the glass that was in the original frame. From: http://www.cassidyframes.com/parts/parts.html shipping was free in month of Jan 2002
