Came across this display case at etsy.com
They have from 1 coin to up to 6 coin display case.
A bit pricey but would look nice to display a favorite coin or medal.
Just thought I'd share.
I like it!
Might not be chemical free, nice but might tone coins one way or another.
Nice for displaying a group of coins.... Certainly the recent different ASE's would look nice there... Too bad only one side can be displayed though. Cheers, RickO
