CONTAMINATION?

Question to all the long time members about storing slabs. I have many slabs in safe deposit boxes, and this particular place does not climate control there safe deposit area. None of the others in town do either. This is the question, I usually have 4 to 5 slabs held together with a rubberband. Will the rubberband damage the slab or the coin through disinegration or release of gases either on the coin or the holder?

I look forward to feedback, oh! almost forgot, this is one of my latest.

As always, thanks for reading my journal and super thanks for looking at my sets.
