Instead of glazing on front and back, this client wanted a solid walnut background and the case was designed to hang on the wall. A recessed french cleat was added in the back and with the cleat, it could be easily hung on a wall for display. This was for a single coin from Artifacts and the size was 4" square x 2" deep. The front frame attaches with hidden magnets and opens the case so the coin can be positioned in the mount. And the removable frame houses the glazing, a thin sheet of framing glass. The coin in the photos is mine and used because it was close to the size of the client's coin, a silver 4 Reales and I used it as a stand-in to design the coin mount.
