In July 1912, word of the new design became publicly known, and coin-operated machine manufacturers sought information. Replying to the inquiries, MacVeagh wrote that there would be no change in the diameter, thickness, or weight of the nickel. This satisfied most firms. However, Clarence Hobbs of the Hobbs Manufacturing Company, of Worcester, Massachusetts requested further information. According to Hobbs, his firm was the manufacturer of a device which would detect counterfeit nickels inserted into vending machines with complete accuracy. Discussions continued for most of the rest of 1912, with Hobbs demanding various changes to the design, to which the artist was reluctant to agree. When in December 1912, the Hobbs Company submitted a modified design for the nickel, MacVeagh strongly opposed it. On December 18, Roberts officially approved Fraser's design, and the sculptor was authorized to complete and perfect the design, after which he would be paid $2,500 (US$ with inflation) for his work.
