Good question. From reading old COMPUTE! Articles and interviews I would guess the C stood for Cosmetic for the new case design and cream color. I don't think it is Cost reduced because when the 64C started selling to consumers in June 1986 the price actually went up. They raised the price to $199 from $159, what the previous street price was for the 64.
