how much does a quarter weigh

A standard modern U.S. quarter weighs 5.670 grams , which is about 0.2 ounces or roughly 1/80 of a pound.

Quick Scoop: How Much Does a Quarter Weigh?

Think of the quarter in your pocket as a tiny, very consistent metal “brick” the U.S. Mint has carefully engineered. For everyday use today (vending machines, parking meters, laundry), the answer people mean is the modern clad quarter, not older silver ones.

  • Modern U.S. quarter (1965–today): 5.670 grams.
  • In ounces: about 0.2 ounces.
  • In pounds: about 0.0125 pounds (1/80 of a pound).
  • Typical diameter: about 24.26–24.66 mm.
  • Typical thickness: about 1.75 mm.

If all your quarters are real and in good shape, they’ll all be right around that 5.670‑gram mark.

What About Older Silver Quarters?

Before 1965, many U.S. quarters were made mostly of silver, so they weigh a bit more.

  • Common silver quarters (about 1873–1964): 6.25 grams.
  • Composition: about 90% silver and 10% copper.
  • These are now mostly collector or bullion coins and rarely show up in normal change.

So if you put a modern quarter and a silver quarter on a very sensitive scale, the silver one will come out heavier.

Why the Exact Weight Matters

Even though this sounds like a tiny detail, the exact weight plays a big role.

  1. Vending machines & meters
    • Machines “recognize” quarters partly by weight plus size and electromagnetic signature.
 * If the coin were much lighter or heavier, the machine could reject it.
  1. Counterfeit and damage checks
    • If a “quarter” weighs way off from about 5.670 grams (for modern clad coins), it could be fake or badly altered.
  1. Bulk counting and rolls
    • Banks, casinos, and coin counters rely on consistent weight to verify large batches of quarters.

Fun Little Perspectives

To give that number more everyday meaning:

  • 4 quarters (one dollar in change) weigh about 22.68 grams , just under an ounce.
  • 40 quarters (a standard $10 roll) weigh around 226.8 grams , about a quarter of a kilogram.
  • A small handful of 10 quarters is already more than 56 grams — a noticeably heavy pocket.
