I tend to have them only if I've received them in change from a vending machine at the post office. I can't say that I have a preference one way or the other.

I tend to have them only if I've received them in change from a vending machine at the post office. I can't say that I have a preference one way or the other. Back 30 years ago I longed for the Washington Metro Farecard machines to accept them--in those days you about had to send your bills had to be all but starched and ironed before the machines would accept them. The technology improved tremendously, but as far as I know the machines still don't accept dollar coins.
