In 1943, this coin turned up among the remnants of Virgil Brand's remarkable hoard. The fertile Burdette G. Johnson archives provide the first documentary appearance of thiscoin since it was published in the American Journal of Numismatics in 1869. Arthur L. Gray, a druggist from Saginaw who continued to collect even after he consigned a superbcollection to the February 1939 J.C. Morgenthau & Co. sale, was sent this coin on August 23, 1943.
