Coins Per Roll

How we verify

How we check the numbers on this site:

  1. Coin weight, size and metal. They come from the U.S. Mint’s Coin Specifications page (penny 2.50 g, nickel 5.00 g, dime 2.268 g, quarter 5.67 g, half dollar 11.34 g, dollar coin 8.10 g, with their diameters and thicknesses). We read the page on 12 November 2026.
  2. Coins in a roll. A roll of quarters holds 40 coins, dimes 50, nickels 40 and pennies 50, as listed on the U.S. Mint’s coin-counting page. For half dollars (20 coins) and dollar coins (25 coins) we have only search summaries of an official release and report, not the pages themselves. Those two are marked on the pages until we have opened the official source.
  3. Bills. The weight of a note, about one gram whatever the denomination, comes from the Bureau of Engraving and Printing FAQ. The size, 6.14 by 2.61 inches, is on the U.S. currency education site uscurrency.gov. The thickness, .0043 inch, and the 454 notes per pound come from an older copy of the Bureau’s FAQ that the U.S. government web archive saved on 15 October 2004; the current bep.gov FAQ does not repeat them. Stack heights are the number of notes times that thickness, so they are for a flat, tight stack: real stacks are often taller because notes curl and trap air.
  4. Gold bars. The standard bar size and weight, 7 by 3 5/8 by 1 3/4 inches and about 400 troy ounces (27.5 pounds), come from the U.S. Mint’s Fort Knox page. The 350 to 430 troy-ounce range of a Good Delivery bar, the 995 fineness and the troy ounce of 31.1034768 grams come from Federal Register notice 86 FR 22996.
  5. Calculations. Roll value is the number of coins times the face value. Weight is the number of coins or bills times the weight of one. Pounds and ounces use the standard definitions (1 pound = 453.59237 grams, 1 ounce = 28.349523125 grams). The formula is shown next to each calculator.
  6. Source and date. Under every result we name the source page and the date we checked it. Where a figure comes from an archived page we say so.
  7. Real coins and bills vary. Official figures are for new coins and notes. Worn, damaged or special coins can differ. Older coins made of other metals weigh differently and are not covered unless a page says so.
  8. When we cannot confirm a number. We leave it out or mark it, and add it when we find the official source.
