How to Count US Coins Fast — A Complete Guide
If you've got a jar of mixed US change — or a register drawer at the end of a shift — counting by hand is the slow way. The fast way is to weigh each denomination on a kitchen or pocket scale and let an app turn grams into dollars. This guide gives you the exact US Mint weights, the scale you need, and a 3-step workflow that counts a typical jar in under three minutes.
What scale do you actually need?
Any digital kitchen or pocket scale that reads in grams works. For best results, look for two things:
- 0.1 g resolution. Most kitchen scales advertise this — cheaper scales that only round to whole grams are too coarse for the lighter denominations.
- A flat platform big enough for your pile. A coffee scale, jewelry scale, or any standard digital kitchen scale will do.
You do not need anything specialized — a $10 kitchen scale is enough. The accuracy comes from the math, not the hardware.
The 3-step workflow
- Sort by denomination. Pennies in one pile, nickels in another, and so on. This is the only manual part of the process, and it takes about a minute for a normal change jar.
- Weigh each pile. Place the scale on a flat surface, tare it, drop a denomination, note the grams. Repeat.
- Enter the weights in CoinPouch. Pick USD, then each denomination, and type in the grams. CoinPouch returns the coin count and dollar total instantly. For full step-by-step screenshots, see our How it works guide.
Tips for cleaner, more accurate counts
- Skip badly damaged coins. Set obvious outliers aside for a separate count.
- Weigh similarly worn coins together. Heavy circulation rounds off edges, so grouping similar coins yields a cleaner count.
- Use the PDF export for any count you'll need to reconcile later — bookkeeping, charity drives, vending route closures.
Frequently asked
Is it more accurate than counting by hand? For sorted piles, yes — humans miscount around 1 in every 50 coins, but a calibrated scale doesn't. See our FAQ on accuracy.
Can I count bills too? Yes. CoinPouch has a separate cash mode for banknotes. Read Coin by Weight & Cash Counter App in One.
Will it work for euro / pound / yen? Yes. 11 currencies are built in. See the full list in our FAQ.
