Coinstar machines are automated kiosks that allow users to exchange their coins for cash or gift cards. The machines have become increasingly popular over the years, as they offer a convenient and fast way to get rid of unwanted coins. But how accurate are these machines? Is it possible that they could be wrong? In this article, we’ll discuss the accuracy of Coinstar machines and look at some tips to ensure you get the most out of your coin counting experience.

What Is a Coinstar?

Coinstar is an American company that operates coin-counting kiosks in supermarkets and other retail outlets across the United States. These kiosks allow users to quickly convert coins into paper money or store credit. The machines accept all types of coins, including pennies, nickels, dimes, quarters, half-dollars, and dollar coins. These machines are operated by the company Coinstar, which operates more than 20,000 kiosks in the United States and Canada.

The process is simple: the user inserts their coins into the machine and the machine counts them up. The machine then prints out a receipt with the total value of the coins. The user can then choose to receive the value of the coins in cash or store credit.

How Accurate Are Coinstar Machines?

Coinstar machines are generally very accurate when it comes to counting coins. They use sophisticated technology to sort and count the coins and calculate their value. According to Coinstar, the machines are accurate to within one cent. In other words, if you deposit $6.97 worth of coins, you will receive $6.97 in cash, a gift card, or a store credit.

Coinstar machines also have built-in safeguards to prevent fraud. The machines are programmed to reject counterfeit coins, which helps protect customers from receiving less money than they expected.

If you’re looking for more accurate coin-counting options, there are several alternatives available. Some banks offer coin-counting services, although they usually charge a fee for their services. And some retailers, such as Walmart, have self-service change counting machines that can provide more accurate results than Coinstar machines. These machines are typically free to use, but they may require that you purchase something from the store before you can access them.

Tips for Getting the Most Out of Your Experience

When using a Coinstar machine, there are a few things you can do to make sure you get the most out of your experience. First, make sure that your coins are clean and free of debris before putting them into the machine. Coins that are dirty or covered in debris may not be counted properly, resulting in inaccurate results. Additionally, try to avoid putting too many coins into the machine at once, as this can slow down the process and cause the machine to stop counting.

It’s also a good idea to check your receipt after the coins have been counted. Make sure that the number of coins and the value listed on the receipt matches the amount you put into the machine. If something doesn’t seem right, you can contact the store or Coinstar customer service for assistance.

Finally, if you are exchanging your coins for cash, make sure to check your bills for any signs of counterfeiting. Counterfeit bills can sometimes slip through the cracks, so it is important to inspect your money carefully before leaving the store.

Are There Any Fees With Using Coinstar Machines?

Yes, there is a fee associated with using Coinstar machines. Customers must pay a service fee of 9.8% of the total value of the coins deposited. For example, if you deposit $4.37 worth of coins, you will receive only $3.93 in cash, a gift card, or a store credit.

The fee is waived, however, if you choose to receive a store credit instead of cash or a gift card. If you choose to receive a store credit, you will receive the full value of the coins deposited.

What Other Services Does Coinstar Offer?

In addition to its coin counting services, Coinstar also offers other services. For example, the company has partnered with Amazon to allow customers to exchange coins for Amazon gift cards. Customers can also donate their coins to charity through the Coins That Count program.

Coinstar also offers a mobile app, which allows customers to check the value of their coins before visiting a kiosk. The app also provides coupons and discounts at participating stores.


Coinstar machines are highly accurate and reliable. They are designed to sort and count coins quickly and accurately and provide customers with the full value of their coins in cash, a gift card, or a store credit. However, it is important to take certain precautions when using a Coinstar machine, such as making sure your coins are clean and checking your receipt and bills for any discrepancies. By following these tips, you can help to ensure that you get the most out of your Coinstar experience.

    I’ve used coinstar many times..trusting it. One time I had a bucket of change and it only registered 18.87. I get gift cards and couldnt redeem too light. Then I decided to check it next time. I counted 35. 75 and received 28.10. Then 3rd timeI decided to feed it a cpl of quarters at a time. I had many. Each time it register as nickels…it’s a Total rip off and someone’s making a lot of money from unexpected people who trust this company. I’m a 70 year old woman. It’s not right. Someone should investigate randomly the machines. This one is in Cocoa Fl at Clearlake.

    I’ve tried/used Coinstars multiple times. Never once have they ever come close to being accurate and never, ever in my favor. I tried a counted roll of quarters, slowly, normal, and quickly before just to test it. Never once did it come up with $10.00.
