1836 First Steam Coinage Medal. Mar 23/Feb 22 Date. Bronzed Copper. 28 mm. By Christian Gobrecht. Julian MT-21b. Thick Planchet. Specimen-64 BN (PCGS).A third example from these dies, this specimen on an exceptionally thick planchet. Gorgeous reddish-copper surfaces are fully struck with a smooth satin finish. Were it not for a few light carbon deposits on the reverse, this otherwise pristine-looking example would likely have secured a full Gem grade from PCGS. Lovely!
