Why I Throw Away my Change

I throw away my change. Not all of it. Quarters of the lifeblood of laundry, and dimes have the best value to weight ratio, but I throw away all nickels and pennies.

If I'm at a store and I don't accidentally autpilot pocket my change, I'll leave the pennies and nickels on the counter. If I'm elsewhere I'll put them on a ledge or on top of a trash can where someone else will find them. But if I'm in my house and they're in my pocket, I just chuck them in the trash. I also do this for foreign currencies of similar denomination (Japanese one and five yen coins, for example).

Let's say that I use cash one hundred times per year. Half the time I'm buying something that rounds out to a dollar amount, and change doesn't factor into it. This is mostly street vendors which either don't charge tax or roll it into the price.

So fifty times per year I'm getting change. It would be interesting to think about the distribution of the "cents amount", but let's just assume that it's evenly distributed from 0 to 99 cents.
