The lyrics were a reference to the scrip system that was common in American coal towns in the early 20th century. Scrip was privately issued currency, usually in the form of metal tokens, redeemable only at the company store. Miners could "draw scrip" from the company in the form of tokens, essentially receiving credit against future wages.
