How often do you use coins for monetary transactions?
Lots of people receive coins in change, but how often do you actually count out and give others coins as part of a transaction? Throwing them in a bucket and taking them to the bank once every few months isn't what I'm talking about.
Paying for a $10.47 lunch with two fivers and $0.47 in change counts. Receiving $0.27 in change when using a $5 bill for a $4.73 soda and candy bar does not count. Paying tolls with physical coins counts. Using coins for bus fare counts.
