Quality Mylar Coin Holders - Pack of 25 - 20mm

A Pack of Twenty Five ( x25 ) 2" x 2" Quality Mylar Coin Holders with a Window Diameter of 20mm.

The frame of the holder is a rectangle of stiff cardboard with two circular holes sized for the coin.  Sealed to the back surface is a thin sheet of transparent Mylar plastic.  The protected coin is sandwiched between the two halves of the holder when they are closed over it, like the covers of a book.  The close can be temporary with staples, or permanent with contact adhesive.  The closed holder is a square with sides 2 inches or 50mm. 

These Mylar sheets are guaranteed to be free of corrosive chemicals.  Ordinary soft plastic holders are made made from PVC which contains chlorine and will damage your coins over time.  Copper coins become coated with an oily green film.  Silver coins turn milky white.  Once this happens, there is no way to reverse the damage.

Protect your coins, and allow others to enjoy your collection – for ONLY 80 cents a coin.  Buy several coin storage products and get FREE postage - see below.
