What is your opinion of preserving/protecting mint chips in black chip insert sheets and then having it professionally framed w/ UV protection glass. I am getting ready to do so with a portion of my collection. I was wondering if the black dye from the chip insert sheet might "bleed" over time on the chips edges.
I know I need to keep these pictures out of sun/bright light.

Has anyone here done this and then checked their chips after a long time too see if that happened?

Please let me know your opinion.

Thanks,
Christopher M. Graham
