Am I The Only One Who Thinks That, If A Coin Wasn't Found In Saltwater It Shouldn't Have"Toning"

Even if you put a coin in a protective case the moment it's struck. The oil in the metal at point of manufacture, would stop the coin from "toning".

to the CCF!

Toning is caused by exposure to chemicals in the atmosphere. The coin does not have to be in seawater.

Toning is also caused by washing coins, and the amount of clearly cirrculated coins that are so clean it's impossible to think they haven't been washed. Toning occurs when water comes in contact with the oils on the surface of the coin. Not just saltwater, freshwater does it as well. That's why the coin in the bank vault bag touching the bag toned, more than the others. At some point that bag came in contact with water. Some rich collector got conned and to try and make the money back, they've managed to get the sheep follow.

I live in greater Sydney. I was given some Penny's and smaller coins from the south pacific when I was 10. Now at 53 the coins don't have toning. For the last 20 years they've sat in a matchbox in a box in storage, before that they sat in the same matchbox in a drawer. The 4 of the 1964 Penny's haven't toned nor the 55 (no dot) hasn't toned either.
