[QUOTE="TypeCoin971793, post: 4779974, member: 78244"]It doesn’t flake off. It is rock hard. I literally have to use a sharp metal tool to chip it. Nothing else would work. No patina would survive a sharp metal tool the original exposed area was polished smooth, but it still has pitting. The newly-exposed area has a fine porosity along with pitting. Yes you can. See above. TiO is a naturally-occurring compound in soil. It showed up when XRFed in an area with a lot of patina. When the coin was XRFed in an area with little patina, very little Ti showed up. This coin is genuine.[/QUOTE]
