ABSTRACT:
A device for encasing coins in protective envelopes embodying a generally rectangularly contoured housing elevated at one end and stepped down intermediate its ends to provide a flat work surface offsetedly spaced below the elevated end, with insulation flatly superposed on the work surface thereof and heating coils embedded therein and encircling a centrally disposed coin receiving area. A generally rectangular forming member pivotally mounted to the elevated housing end and overlying and elevatable relative to the work surface. With a coin sandwiched between two sheets of plastic and disposed in the coin area, the forming member is actuated downwardly to compress the plastic sheets over and around the coin and against the flat work surface, and switching pin means on the forming member coacts with selective switching means to make contact with and energize a selected heating coil so that the heat therefrom circumferentially severs the plastic sheets around the coin and the latter is encased in a compact circular package conforming to the size of the coin.
