Weight of a Quarter in Grams, Plus Every US Coin

A modern US quarter weighs 5.67 grams, and once you know that number you can do a surprising amount without a physical scale. The weight of a quarter is fixed by the US Mint, so a small stack of them becomes a reliable reference for calibrating a scale, counting change, or estimating other small objects.

This guide lays out the weight of every circulating US coin in grams, what a full roll weighs, and how to count coins by weight instead of by hand. Every figure here traces back to published US Mint specifications, so you can trust the numbers down to a tenth of a gram.

The Weight of a Quarter and Why It Matters

The weight of a quarter is 5.67 grams for every 25-cent piece struck since 1965. That works out to almost exactly 0.2 ounces, so 100 quarters weigh 567 grams, or about 1.25 pounds. Because the figure never changes, a handful of quarters makes a handy calibration weight for a kitchen or jewelry scale.

Knowing the weight of a quarter in grams is more useful than it sounds. To convert that into imperial units, run it through a grams to ounces converter: 5.67 grams lands at 0.2 ounces per coin, so four quarters come to roughly 0.8 ounces.

A modern quarter weighs 5.67 grams. Stack 100 of them and the pile weighs 567 grams, a reference you already carry in your pocket.

Once you trust the number, the practical uses stack up quickly, from calibrating a scale to sizing up a jar of loose change before you haul it to the bank.

How Much Does a Penny, Nickel, and Dime Weigh?

How much does a penny weigh? A penny weighs 2.5 grams, the lightest of the low-value coins. How much does a nickel weigh by comparison? Exactly 5 grams. And how much does a dime weigh? Just 2.268 grams, which makes the dime the lightest circulating coin even though it outvalues both the penny and the nickel.

The nickel is the odd one out because 5 grams is a round, deliberate number. The US Mint has kept the nickel at exactly 5 grams since 1866, which is why science teachers still hand one to students as a classroom reference weight.

Why Pre-1982 Pennies Weigh More

Pennies made before 1982 weigh 3.11 grams because they were 95 percent copper. In 1982 the Mint switched to copper-plated zinc and the weight dropped to 2.5 grams. If you weigh a jar of pennies and the average comes in high, you are holding older copper cents.

Full US Coin Weight Chart in Grams

Here is every circulating US coin, its weight in grams, and its diameter in millimeters. These are the official specifications, so a brand-new coin should match them almost exactly.

To turn these into ounces, a quarter at 5.67 grams is 0.2 ounces and a half dollar at 11.34 grams is 0.4 ounces. For heavier stacks, our grams to pounds tool does the math, and you can confirm every figure against the U.S. Mint coin specifications.

How Much Does a Roll of Coins Weigh?

How much does a roll of pennies weigh? Fifty pennies come to 125 grams. A standard roll of quarters holds 40 coins worth 10 dollars and weighs about 226.8 grams. And how much does a roll of dimes weigh? A 50-coin roll lands at roughly 113.4 grams. Banks rely on these fixed counts so tellers can weigh rolls instead of counting them by hand.

Quick Roll Weight Rules of Thumb

If you want to shortcut the math, a roll of nickels weighs 200 grams because 40 nickels at 5 grams each is easy to picture. A roll of quarters and a roll of half dollars both land near 227 grams even though they hold different coin counts.

A full roll of quarters weighs about 227 grams. Weigh the roll, divide by 5.67, and you have counted 40 coins without opening it.

Silver Coins Weigh More Than Modern Ones

Older silver coins are noticeably heavier than the copper-nickel coins that replaced them. A pre-1965 silver quarter weighs 6.25 grams versus 5.67 grams today, and that silver quarter weight difference is the fastest way to spot one by feel or on a scale.

The gap is wider for larger coins. A silver Morgan dollar weighs 26.73 grams, while a modern golden dollar coin weighs just 8.1 grams. How much does a half dollar weigh today? A copper-nickel half dollar comes to 11.34 grams, and the 90 percent silver half dollars minted through 1964 were heavier still.

Count Your Coins by Weight the Easy Way

Counting coins by weight is simple: weigh all the coins of one type, then divide by the weight of a single coin. Fifty quarters that weigh 283.5 grams divide cleanly by 5.67 to give you 50. A quick phone estimate gets you close, and a scale reading to a tenth of a gram makes it exact.

Accuracy comes down to your scale. For coins you want a readout to at least 0.1 grams, and 0.01 grams is better, because rounding to whole grams throws off the count. Worn coins also weigh slightly less than new ones, and the Mint allows small tolerances, so mixed handfuls drift a little. This guide to counting money by weight explains the method banks use.

Weigh 100 dimes, divide 226.8 grams by 2.268, and the scale has counted your change for you.

Coin Weight Questions, Answered

How much does a quarter weigh?

A US quarter weighs 5.67 grams, or about 0.2 ounces. Every quarter minted since 1965 uses the same copper-nickel blend, so the weight is consistent whether the coin is fresh from the bank or decades old.

How much does a roll of quarters weigh?

A standard roll of 40 quarters weighs about 226.8 grams, or roughly half a pound. Because the count is fixed at 40 coins, a bank can weigh a sealed roll to confirm it holds the full 10 dollars.

How much does a dollar coin weigh?

A modern golden dollar coin weighs 8.1 grams, lighter than the 26.73-gram silver dollars of the past. The reduced weight made the coins cheaper to produce and easier to carry in a pocket.

Does a worn coin weigh less than a new one?

Yes, but only slightly. Circulation wears away tiny amounts of metal, and the US Mint already allows small weight tolerances at striking. For counting by weight, that difference rarely changes the result once you round to whole coins.
