I good to see discernment being used when talking about the concept of cleaning coins.

We hear never ever, ever, ever, (ad infinitum) clean coins so often that people forget when there is no value to lose, and the coin looks horrible, then go ahead and try.

Great job on these.

Thank you for your thoughts! I am glad everyone enjoyed it!

Basically you've soaked them in acid which stripped off the remaining zinc, broken down the Iron oxide and possibly a thin layer of the steel, and then polished off the residues with the cloth. Leaving just the bare steel surface. Lemon juice is a fairly strong acid with a pH of 2 (The lower the number the stronger the acid. Acids run from 1 to 7 and Bases from 7 to 14. 7 is neutral. The higher the number over 7 the stronger the base. Lye is 13.).

Also, pretty cool to know what is actually happening, great insight Conder101!
