Buck's appearance here introduces the concept of the Dollar-mation dog, similar to a Dalmation, but with dollar signs instead of regular black spots. While Overstreet and other sources cite a second appearance for Buck on the cover of Richie Rich (1960 series) #65, that dog does not have the characteristic dollar signs and there is no indication that the dog is named Buck. Richie would later get his own Dollar-mation dog, Dollar, who went on to appear in many stories across the full range of Richie's titles.
