This is the famous 1836 Gobrecht dollar with "C. GOBRECHT F." in the exerge below the base. The obverse die was originally believed to predate the "name on base" die used on J60/P65 but analysis of several examples by John Dannreuther in 2007 showed that this die and also the 1838 & 1839 dies originated from the same master die (see JA1836-5/P3028) and hub with Gobrecht's name on the base, thus its creation date is likely no earlier than 1837, and, may in fact be, much later. The base shows extensive graver marks on it as shown in the image below. For additional information on this click here. As for the C GOBRECHT F, it would be interesting to compare the lettering here with the 1840 hub splasher JA1840-4/P3073 to see if they are the same, ie made from a gang punch. These findings cast doubt on just when this die was actually made since no examples were known prior to the late 1850s. The first appearance for one of these is believed to be Ed Cogan's 1859 sale of the Joseph N.T. Levick collection. Cogan is also the source for there being 18 examples struck. Was this a story given to Cogan by a Mint official to make these appear more legitimate? It also explains why no original in alignment I has ever been found - none were made ! Some 3 to 4 dozen examples are believed to exist today. The earliest ones were struck in die alignment IV. They are rarer than those struck in die alignment III which are believed to have been struck in the mid-to-late 1860s or early 1870s along with the copper examples of J59/P62 of which at least 2 are confirmed to exist. For additional information on this and all copper Gobrecht dollars, click here. All examples seen, regardless of alignment, show die cracks through "NITED STATES O" and through the "OLLA" in "DOLLAR". Later examples show a raised die mark (rust?) between the left and right base of the "A" in "States" while the very latest examples show extensive work by STATES which thinned the crack, removed portions of the denticles and partially removed the raised die mark between the base of the "A". This is visible on the Eliasberg example as shown below. The Eliasberg coin establishes that some examples of J58/P61 represent the last use of this reverse die as it was struck later than any known 1838 or 1839 dated muling.
