Solid 925 Sterling Silver Bezel is made for 39mm x 3 mm thick coins like most 1 oz. round silver bullion and Casino Chips. This Coin Bezel holds your coin with prongs at the back.. Made in the USA . This is a very simple light and unobtrusive bezel that has a rounded edge and a very thin rim to show the whole coin. The coin can be removed and replaced safely and at any time but repeated openings and closings will damage the prongs.
