Like I said, I don't know enough to dismiss the claims out of hand, but I am a little puzzled that they aren't more widely cited. All the...
Based on the photo and Coinflation, as of this afternoon, 2.47 cents.
Well, maybe you come across photocatalyzed metathesis reactions between water and simple ketones on a frequent basis, but it was certainly news to...
That's the idea, assuming it didn't contain any dissolved residue to begin with, and didn't dissolve anything off of other areas of the coin.
*blink* *blink* :eek: That's... astonishing. I've googled around a bit, and I don't see a lot of support for this outside of the original...
Not to pick nits, but I'm pretty sure this can't happen. You'd need some pretty exotic chemicals to oxidize acetone without flat-out burning it...
The 91% isopropanol is a constant-boiling mixture, or "azeotrope", with water. What this means is that it does contain water, which can react with...
Well, it looks like SOMEONE was suspicious -- eBay's already killed the listing. Was this, by chance, a Chinese seller listing "10 available"?...
Auditioning a new avatar, are we, Detecto? :headbang:
...or at least "more perfect". :rolleyes:
Ouch, that hurts! Thanks for the reminder...
I'm not seeing circulation wear in this photo. Maybe two spots on Liberty's face, but I've seen much worse on coins slabbed as MS. I'd guess 63.
Yep, pretty much. Or you could always heat them and see which ones melt, or cut them open. :)
Yeah, but my wife likes the fancy imported cheese, and the way those prices run, it should be measured by the troy ounce...
I think that's when someone beats on a coin or otherwise abuses it...? :devil:
I'd expect acetone to work better than alcohol. Try that first.
For maximum confusion, couldn't you have gotten a 1965 set in MS-65, a 1966 set in MS-66, and a 1967 set in MS-67? :devil:
I was going to ask for some references supporting this, but I think your original thread at CU pretty much covers it:...
From the discussions I've read here, that's not necessarily true. I have the impression that the traces of cleaning stick around even after a good...
Don't panic. If this is what it is, the mercury is bound -- "amalgamated", or alloyed -- into the surface. The only way to get a toxic amount out...
Separate names with a comma.
