look at this beautiful 1968 d half dollar. Now is it a TDO half dollar? because a couple people said it looked like one and it looks like one to me. Thanks Noah
How it occurs ? I also have some slabs which have such occurrence which reduces value of coin. Is there any way to restore original condition?
It cannot be restored to the original White look, but it also should not reduce the value. If anything, toning would increase the value. The amount of increase would be based on the look of the coin.
@Noah Finney, you have a beautiful coin, the pattern is just a little different than what I'm accustomed to seeing. Take a look at these 1964s. They're what I'm seeing. Look at this 1966, too, for a 40% (a little over-exposed; sorry about that)...
It was at the end of a fold-over paper roll. I don't have any currently but the pattern is typical EOR toning and plentiful without too much searching.
Well, you seem like such an honest guy, I'll trust you on that. Except I didn't doctor mine by intentionally hastening the toning like that, mine never touched paper. No wonder though this "EOR toning" looks a little thin, without much body to it.
It's "End of Roll," I think. Maybe one of our acronym-speaking experts can confirm that for us language-speaking dopes.
