ODYSSEUS101

Hi everyone & thanks for having me on here, I’ve recently began collecting pre-decimal silver coins leaning mainly towards half crowns EF or better. Having found that the auctions seem to be the place to purchase good quality coins I’m starting to worry a little on storage. Having looked around & reading a little I’ve went for acrylic cases but also with the white foam inserts to secure in place. ( bought on eBay ) I just wanted to ask anyone more experienced whether they know if the foam inserts can cause any long term issues with the coins. Any help will be greatly appreciated. Thanks
