Even before 1848, record amounts of gold were flowing to American mints to be struck into coin, but the California Gold Rush vastly increased these quantities. This renewed calls for a gold dollar, as well as for a higher denomination than the eagle ($10 piece), then the largest gold coin. In January 1849, McKay introduced a bill for a gold dollar, which was referred to his committee. There was much discussion in the press about the proposed coin; one newspaper published a proposal for an gold dollar; that is, with a hole in the middle to increase its small diameter. McKay amended his legislation to provide for a double eagle ($20 gold coin) and wrote to Patterson, who replied stating that the annular gold dollar would not work, and neither would another proposal to have dollar piece consisting of a gold plug in a silver coin. Nevertheless, Gobrecht's successor as chief engraver, James B. Longacre, prepared patterns, including some with a square hole in the middle.
