1836 First Steam Coinage Medal. Original Feb. 22 Date. Copper. 28 mm. By Christian Gobrecht. Julian MT-20a. Specimen-15 (PCGS).A predominantly copper-gray example with glints of lighter sandy-brown intermingled throughout the right half of the reverse. Scattered handling marks on both sides, minor disturbance at the reverse border outside the letter U in UNITED. This is the scarcer variant of this medal, the fact that we are offering multiple examples in this sale significant.
