My husband, also a "bean counter" was also put out that Coin Star took 10% of the take of the coins counted. I've found an alternative. My local bank, Wells Fargo, has coin counting machines and if you have an account with them, usually the tellers will be happy to dump the coins in the machine if they aren't unusually busy--for free.

If one chooses to donate, why not donate 100%?
