This struck me as sort of interesting, possibly useful, and probably a little compulsive. One blogger’s way of slowly using change is to carry the optimal number of each denomination of coin in his pocket.
Everyone has coins they want to get rid of. I randomly thought of an easy way to carry change and always have enough change for a purchase. For the sake of this article, I consider change to be less than $1 of coins. To be able to make any change combination, you need to carry $0.99 of change through 10 coins…
I almost never pay with exact change, but that’s probably because I find a sick satisfaction in rolling my coins every few months and taking them to the bank. I crave that big mountain of coins because when I was a kid it was easy to imagine a big pile of coins were treasure.
