Mounting a coin has never been easier! Supersafe brand coin holders utilize modern technology, enabling you to self seal each holder just by simply folding and pressing together. Archival-safe and completely inert, they help maintain the luster and grade of your coins. Each economical 2 1/2" x 2 1/2" holder displays both sides of your coin, and can be labeled with a felt tip marker. Handy tabs make it easy to insert and remove the holder from the PVC-free coin pages. And the flexible film even accommodates thick medals or ancients. (Sold in packs of 50).
