 In January 1844 , North Carolina Representative James <unk> McKay , the chairman of the Committee on Ways and <unk> , solicited the views of Director Patterson on the gold dollar . Patterson had more of Gobrecht 's pattern dollar struck to show to committee members , again advising against a coin that if issued would be only about a half inch ( 13 mm ) in diameter . He told Treasury Secretary John C. Spencer that the only gold coins of that size in commerce , the Spanish and Colombian half @-@ <unk> , were unpopular and had not been struck for more than twenty years . This seemed to satisfy the committee as nothing more was done for the time , and when a gold dollar was proposed again in 1846 , McKay 's committee recommended against it .
