How many nickels are in a dollar?
Twenty. A nickel is five cents, and twenty fives make a hundred. That single ratio drives every other answer on this page: $2 is 40 nickels (one roll), $5 is 100 nickels, $10 is 200, and $20 is 400. Going the other way, convert nickels to dollars by dividing the count by 20.
The mental shortcut most people find easiest is not division by 20 at all. Halve the number of nickels, then move the decimal point one place left. 340 nickels → half is 170 → $17.00. It works because halving and then dividing by ten is dividing by twenty, and halving is something everyone can do without a pen. Try it on the awkward ones: 137 nickels → 68.5 → $6.85, which is exactly what the calculator above returns.
Nickels in dollars — quick reference
| Nickels | Dollars | Weight |
|---|---|---|
| 1 | $0.05 | 5 g |
| 2 | $0.10 | 10 g |
| 5 | $0.25 | 25 g |
| 10 | $0.50 | 50 g |
| 20 | $1.00 | 100 g |
| 40 | $2.00 | 200 g |
| 50 | $2.50 | 250 g |
| 100 | $5.00 | 500 g |
| 200 | $10.00 | 1,000 g |
| 400 | $20.00 | 2,000 g |
| 500 | $25.00 | 2,500 g |
| 1000 | $50.00 | 5,000 g |
Notice how clean the weight column is. That is not a coincidence, and it is the nickel's one genuinely useful quirk — see below.
The nickel weighs exactly 5 grams
A U.S. nickel weighs 5.000 grams. It is the only circulating American coin with a whole number of grams: the dime is 2.268 g, the quarter 5.670 g, the half dollar 11.340 g, the cent 2.500 g. That makes the nickel the one coin you can genuinely count with a kitchen scale and no arithmetic worth mentioning.
100 grams is 20 nickels, which is $1.00. A full roll of 40 weighs exactly 200 grams and is $2.00. A kilogram is 200 nickels, or $10.00. There is no rounding step anywhere in that chain — the numbers are exact, not approximate. A pound of nickels, if you prefer imperial, is 90 coins and $4.50.
Because it is so reliably 5.000 g, the nickel doubles as a calibration weight. Anyone who has needed to check a small scale and had no calibration mass to hand has stacked nickels on it: ten of them is 50 g, and the tolerance is far tighter than most kitchen scales can resolve.
Rolling nickels: 40 to a roll, $2 a roll
A standard roll of nickels is 40 coins, $2.00. The U.S. Mint's coin glossary gives the full set — 50 cents, 40 nickels, 50 dimes, 40 quarters, 20 half dollars, 20 dollar coins. Nickels and quarters both come 40 to a roll, which catches people out constantly: the 50-coin habit from pennies and dimes does not transfer, and an over-filled wrapper will not crimp shut.
The counts were chosen so the face value lands on a round number rather than the coin count. Fifty nickels would be $2.50; forty is a clean $2.00, and a bank box of 50 rolls is exactly $100. If you are rolling change to deposit, that is what the teller expects to receive.
Why the five-cent coin is called a nickel
The first U.S. five-cent piece was not a nickel at all. It was the silver half disme (pronounced "dime"), much smaller than today's coin, and it carried Liberty on the obverse with an eagle — later a wreath — on the reverse. In 1866 the Mint began striking a larger five-cent coin from nickel and copper, and the public promptly named the coin after its metal. The silver half dime carried on alongside it until 1873, then disappeared.
The design history since then is unusually well known: the Buffalo nickel from 1913 to 1938, with a Native American chief on one face and a bison on the other; Felix Schlag's Jefferson and Monticello from 1938; the Westward Journey series in 2004 for the bicentennials of the Louisiana Purchase and the Lewis and Clark expedition; and the current "Return to Monticello" design since 2006.
There is one wartime oddity worth knowing if you are sorting a jar. Nickel metal was needed for the war effort during the Second World War and was taken out of the five-cent coin entirely. To mark the change the Mint moved the mint mark to a large letter above Monticello's dome — and put a "P" for Philadelphia on a coin for the first time in its history. Those wartime pieces contain silver, so a five-cent coin with a big letter over the dome is worth setting aside rather than spending.
What today's nickel is made of
Unlike the dime, quarter and half dollar, the nickel is not a clad coin. There are no layers: it is a single homogeneous alloy of 25% nickel and 75% copper all the way through, which is why its edge is plain and shows no copper stripe. It measures 21.21 mm across and 1.95 mm thick, making it the thickest of the small change.
Both the nickel and the cent have spent years costing more to make than they are worth, which is why melting or exporting them is prohibited under 31 C.F.R. § 82.2(f) — a restriction the Mint still publishes and enforces through a licensing process. The cent lost that argument outright: circulating penny production was suspended after the cost of making one reached 3.69 cents.
Common mistakes
Using 50 coins per roll. That is the penny and dime figure; nickels are 40. Confusing the nickel's size with its value. It is physically bigger than a dime but worth half as much — a fact that trips up children learning coins and adults counting quickly. And adding decimal money in a spreadsheet without rounding: this calculator works in whole cents precisely so that 137 nickels reads $6.85 and never $6.850000000000001.
Frequently asked questions
- How many nickels are in a dollar?
- Twenty. A nickel is 5 cents, and 20 × 5¢ = 100¢ = $1.00. It follows that $5 is 100 nickels and $10 is 200 nickels — the only US coin where the dollar amount and the coin count differ by a clean factor of 20.
- How much is a roll of nickels?
- A standard roll holds 40 nickels and is worth $2.00. Nickels and quarters are the two denominations that come 40 to a roll; pennies and dimes come 50, half dollars and dollar coins come 20.
- How do I convert nickels to dollars in my head?
- Divide by 20, or — usually easier — halve the count and move the decimal point one place. 340 nickels: half is 170, so $17.00. It works because 5 cents is one twentieth of a dollar, and halving then dividing by ten is the same as dividing by twenty.
- How much does a nickel weigh?
- Exactly 5.000 grams — the only circulating US coin with a whole-number weight in grams. That makes nickels the easiest coin to count on a scale: 100 g is 20 nickels ($1.00), 200 g is a full roll ($2.00), and 1 kilogram is 200 nickels ($10.00), with no rounding anywhere.
- Is it legal to melt down nickels for the metal?
- No. The U.S. Mint states that melting, treating or exporting one-cent and five-cent coins is prohibited under 31 C.F.R. § 82.2(f), with limited exceptions, and melting licences must be requested from the Director of the Mint. The rule exists because the metal in both coins has at times been worth more than the coin.
