I found this penny while roll searching. It weighs 2.57 grams and it looks crazy. I used 2 parts lemon juice and 1 part water on the steel cents I found because it makes them look great. They came out looking great except for this one. It has to be made from something else because all the other steel cents cleaned up nicely by letting them soak overnight in the solution. It looks like the coin was dipped in something. It's almost like a copper penny dipped in something. But it is magnetic. However, it does feel a little less magnetic than before I let it soak in the solution. Look at the picture of it next to the other coin I put in the solution. There were 2 more and they both came out looking nice and clean also. What in the world is up with this coin? does anyone know what I have?
