Without installing a pressing device(33) on the holder(31) of the upper mold(3), a fastening sill(41) is formed on the lower mold(4), and a blocking body(211,221,231) on the bottom of each partitioning body(21-23) of the brim mold(2) is fixed and installed with bolts. Although each partitioning body is to be raised along the surface of the ramp as the brim mold is pushed outside by the expansive force of a burnt coin(1) at a standstill condition of the table(7), it cannot be raised because the blocking body(211,221,231) on the bottom of the partitioning body is caught by the fastening sill. Therefore, the expansive force of the burnt coin cannot open the brim mold, partitioning lines are not marked on the coins formed with this method. Also the setting, work of a mold becomes easier because the pressing device is excluded from the holder of the upper mold.
