Gimme a break; I studied math in school, not physics. :P But, it's no coincidence that when you google "reflective diffraction grating," this...
Actually, as CWTs go, it's rather common. I got a nice AU/MS one with some red left for $60 at a smallish local coin show.
Yeah, those are nice die cracks. But, if you think that's cool, you should try and find a Broas Pie Bakers Civil War token. :) There are...
I'd also love to ditch all the dead presidents, but I'd start with the cent or maybe the nickel. Abe's been on the cent for 107 straight years!...
That's funny. How many 2x2s gave their lives to make that holder? :P
Not a grading instructor, but I have been a teacher. :) @iPen: The watch face is a better model for cartwheel luster than the sun rays. If your...
Yes, exactly. It's as if the planchet were made of very hard Silly Putty. You don't need to heat it up to strike a design on it with a modern...
This comes up every time someone talks about "metal flow," but it's clearly wrong. Silver liquifies at 1,763°F / 961.8°C. There's no way a...

I did some looking a while back on eBay, and, from what I could tell if you wanted one that was reasonably well-centered, with most of the obverse...

Some interesting toning on the obverse. :) I'll say 64.
Are the "chunky" flans really common on these?
I've been curious about aes grave and aes rude for a while. Too bad I don't read Italian well. :( Are there any books on them in English?
Incredible. Very rare, I suppose?
It looks like a spot that might have developed in the holder.
What? Bleach would oxidize the coin, turning it dark.
Could be a small strike thru.
Maybe to match the rest of the collection? There are tons of reasons why coins that are "not worth submitting" end up in slabs. Right now, there...
After looking at all his offerings, I'm starting to suspect they're all cleaned. And I do mean suspect, because with those pictures, I can't...
