There is a regular customer who had his business catch on fire. Still needing clean clothes he brought black coins in for the washers. At first this did not make me happy. Then I realized they were mixing in with all the rest and being paid out for paper bills. And yes to those people who just come in for quarters. Now these things are ugly! So the people who do not want them can put them in the washers. And the other people are stuck with them. Quarter loss has gone down substantially. I am just going to leave them in the mix for a while. They do have to go eventually as they really are not nice to look at.
