Anyone Willing To Do A Dip Experiment For Us?

I posted these before here somewhere. The first one is a pile of pennies from someone that works in a bar and picks these up each night. He usually gives me the pennies and keeps the larger coins.
The first is as they were
The second photo is from a very intensive cleaning with all types of soaps and water in a large bucket, outside of course.
Any addidional cleaning would not be worth the money to do that.

wow Moe, that's a world of difference... I think after seeing some that have been dipped is actually beneficial to the community... We as a community owe it to ourselves, especially the newer collectors to educate not just what this can do, but how to see the difference in coins that have been dipped... I will shut up now, as I don't want to instigate comments away from the topic at hand...

that is some serious difference! how would you tell that the 3 cent has been cleaned or not, if you didn't know that it had been?

I was suprised to see the difference a ten second dip could make on your Three Cent piece. To each his own but I prefer the undipped piece with its old skin and color. But even I would dip a coin that has toned very dark or has enviromental damage that needs to be removed to enjoy. One thing I have tried is lemon juice on brass to remove verdigris and it works.
