How much is your pocket change worth? If you have a money jar, then you know that pocket change adds up fast. The challenge for many is where to bring the change to convert into cash.

Fortunately, Coinstar, the top brand in consumer coin counting, invented self-service coin counting and has locations throughout the United States, Canada, and United Kingdom.

If you want hard cash from a Coinstar machine, you'll pay a commission. To stretch your pennies and avoid a commission use Coinstar for gift certificates at leading stores like Amazon.com, Starbucks, iTunes, and many more.

Coinstar has a charity option where you can donate your change by keying the unique identification number of your charity and pouring your coins into the machine. When Coinstar finishes counting, you will receive a tax-deductible receipt.
