I have a new Y65 Air-Tite in the package if that helps any. Will ship to you, just send postage back when you receive it. Shouldn't be more than a dollar. Let me know.
I have used the Quadrum XL holders quite a bit but they only go up to 58mm. They usually work out to about a dollar each. I would love it if they made larger sizes. https://www.wizardcoinsupply.com/in...h&search_in=all&x=0&y=0&search_str=quadrum+xl
Well it's in the acetone, and I'm going to take @emdems up on his offer, and we'll see how that goes. The other air-tites are fine, but I can't see spending roughly 25% of the coin's value on a holder, at that price I'd be better off getting it slabbed by NGC for not much more. Once it's out of the acetone, it's going into a food grade ziplock, and will lie in wait.
Just a bit of an update. About 30 hours in acetone, and a distalled water rinse, and this is what she looks like; Not perfect, but pretty acceptable. As for protecting it until the generous Air-Tite from @emdems gets here, I was staring at a stack of flips, and came up with this for the wait: It's also in a food grade zip lock bag as well.
Oh, and it's actually a 1970, not a 1969. Have no idea what the mintage is on these for '70. Neither NGC nor Numista have mintage numbers for the 1970 (1969 was 6,720).
