About

Coins Per Roll answers practical questions about US coins, paper money and gold bars: how many coins go in a roll, what a coin, a bill or a gold bar weighs, how big it is, and what a pile of cash adds up to. Each answer starts with the short version and comes with a calculator, so you can try your own numbers.

The figures come from the U.S. Mint and the Bureau of Engraving and Printing. Under every result we name the source and show the date we checked it. Where we could not find an official figure we say so instead of guessing. You can read how we check our numbers on How we verify, the rules we follow on the Editorial policy page, and every page we used on Our sources.

The site is written and kept by the Coins Per Roll Editorial Team. It covers US currency only, so the coin and bill sizes, weights and roll counts here do not apply to other countries.
