The term "copper collar" was used in historical novels set in that period. In "The Old Copper Collar" (1957), a tale of the course of a senatorial election in Helena in the early 20th century, Dan Cushman refers to the "copper collar": "At this point the galleries packed with Bennett sympathizers commenced heckling him with suggestions he wore the Copper Collar, but these hoots and catcalls he contemptuously ignored, reiterated his freedom from all cliques, factions, and corporations and that his purpose had been purely and simply to prove or disprove unlawful practices, and sat down." Even the suggestion that a person wore the "copper collar" created pandemonium from the crowd.
