What we do when we are not selling coins...Part 11.... We are trying to rule out that acid rain has become acid humidity. Corrosion is green and so is Sulphur. There is a lot of gasoline being made from sour crude. The Sulphur content in sour crude is many times higher than in sweet crude. It is illegal to use sour crude gasoline in the USA. It's not illegal to make it. Then export it.

 We have been seeing corrosion on Small Cents. I mean a lot of corrosion. Cashiers don't want to handle these coins. I'm in Southern Michigan. I don't know if this is a Michigan problem or a United States problem. I would like people to email me and tell me what condition their circulating penny's are in. This will continue as I get results.

 Thank you,
