Each dollar bill and coin you hold went through a long journey that included withstanding dozens of tons and pressure and sometimes heat up to 950 degrees celsius.

It’s all part of the business of stopping counterfeiters. The Bureau of Engraving and Printing, which makes the bills you hold, has an efficient operation for that. It’s not quite the same at the US Mint. Are the days of coins numbered?
