Frame-A-Coin DuPont Mylar Currency Holders -- Large

Frame-A-Coin DuPont Mylar Currency Holders are made from DuPont Melinex polyester. Melinex is one of a very few films that have been tested by the Library of Congress and found to be satisfactory for use in encapsulation of paper artifacts. We are aware of no other brand of currency sleeves that uses a film found to be acceptable by the Library of Congress. In addition to its superior archival characteristics, Melinex is produced to DuPont's strict specifications meaning every batch is uniform in color and clarity. As a result, these are the best available currency sleeves. Available with or without a slight lip on the back layer to facilitate opening the sleeve.
