I'm sure that you've heard of the term.."cabinet rub".
It's best to never let anything make contact with any high point on any coin. The rims are definitely in constant contact and that's as good as it gets for contact. ICCS holders as an example. Soft or hard plastic will impart some wear or change of surface luster on the highest contact points with time.
Handling the en-capsuled coins as less as possible is good also.
