About the Coin Counter
This coin counter adds up loose change and cash for you. Enter how many pennies, nickels, dimes, quarters, half dollars and dollar coins you have, plus any $1 to $100 bills, and it returns the total value, the split between coins and notes, how many standard bank rolls each coin fills and roughly how much the coins weigh.
It is useful for emptying a change jar, counting a cash drawer or till at the end of a shift, tallying a fundraiser or piggy bank, or checking what a coin-counting kiosk should pay before its fee. The roll counts tell you how many paper wrappers to pick up from the bank.
Values and rolls follow US currency: 50 pennies, 40 nickels, 50 dimes and 40 quarters to a roll. Nickel, dime, quarter and half-dollar weights are the ones fixed in federal law (31 U.S.C. 5112); the penny (2.5 g, copper-plated zinc since 1982) and the golden dollar coin (8.1 g) use US Mint specifications. Pennies made before 1982 weigh 3.11 g, so the weight of an old mixed jar is an estimate. The US stopped making pennies for circulation in 2025, but they remain legal tender.
With the default inputs, the total value is $25.27. Change any value above to recalculate instantly.
How to use the coin counter

- 2Count each pile — stacks of 10 make this faster.

- 5Use the roll column to know how many wrappers you need for the bank.
Formula and method
Each denomination’s count is multiplied by its face value and the results are added together. Totals are computed in whole cents so pennies never produce rounding errors. Full rolls use the standard US bank wrappers — 50 pennies ($0.50), 40 nickels ($2), 50 dimes ($5), 40 quarters ($10), 20 half dollars ($10) and 25 dollar coins ($25).
Coin weight uses the statutory weights for the nickel (5 g), dime (2.268 g), quarter (5.67 g) and half dollar (11.34 g) from 31 U.S.C. 5112, plus US Mint specifications for the modern penny (2.5 g) and dollar coin (8.1 g), converted to pounds at 453.59237 g per lb. Every penny is assumed to be a post-1982 zinc cent.

Worked examples
A typical change jar
137 pennies ($1.37), 42 nickels ($2.10), 58 dimes ($5.80) and 64 quarters ($16.00) add up to $25.27. The 301 coins weigh about 2.3 lb and fill 5 bank rolls: 2 of pennies and 1 each of nickels, dimes and quarters.
A big jar ready for the bank
That is $5 in pennies, $10 in nickels, $30 in dimes and $100 in quarters — $145 in total. It wraps into exactly 10 + 5 + 6 + 10 = 31 rolls and weighs almost 11.5 lb.
Counting a cash drawer
The coins come to $13.73 ($0.23 + $0.55 + $1.70 + $7.25 + $1.00 + $3.00) and the bills to $164 ($14 + $30 + $20 + $100), for a drawer total of $177.73.
Frequently asked questions
How many coins are in a roll?+
Standard US bank rolls hold 50 pennies ($0.50), 40 nickels ($2), 50 dimes ($5), 40 quarters ($10), 20 half dollars ($10) and 25 dollar coins ($25).
How much does a penny, nickel, dime and quarter weigh?+
A modern penny weighs 2.5 g (US Mint specification), and federal law sets a nickel at 5 g, a dime at 2.268 g and a quarter at 5.67 g. A pound of quarters is about 80 coins, worth roughly $20.
Where can I cash in coins for free?+
Many banks and credit unions accept rolled coins from customers at no charge, and some have free counting machines for account holders. Self-service coin kiosks in stores typically keep a percentage fee of roughly 12% or more, though some waive it if you take an eGift card instead of cash.
What is the fastest way to count change?+
Sort by denomination first, then make stacks of ten coins of the same type. Count the stacks, enter the totals here, and wrap full rolls as you go.
How much is a jar of pennies worth?+
Pennies made since 1982 weigh 2.5 g, so a pound is about 181 coins, or $1.81; older copper pennies weigh 3.11 g, so a mixed jar is worth a little less per pound. A 20 lb jar of pennies is therefore worth only about $29–36. The US Mint stopped striking pennies for circulation in 2025, but existing pennies remain legal tender.
