1-3% of the proof population, amounting to 40,000 - 120,000 coins. I have only one, and I honestly don't remember whether I cherry-picked it from...
More on Peace dollars? I had to dig around a little to see that it's a known problem on some Peace dates. For ASEs, the clamor over it has been...
I'm no expert, but I wonder whether an altered 1895 might look the same. There's definitely damage to the date, but I don't know whether the...
Yeah, I would've taken my chances with the OsO4. At least there wouldn't have been anyone deliberately spraying it at me.
If it were impurities in the alloy, wouldn't you expect them to stretch out during rolling, so you'd see milk streaks rather than spots? Then...
Somebody said they put a shot glass on a plate, then put a bowl upside-down over the glass, forming a little vapor chamber. That seemed like a...
Back when I started, this wasn't the case. In RAW images, Canon cameras were definitely recording valid pixel levels at least a half-stop or more...
I think you'd die first, which of course also causes irreversible blindness. It does attack the cornea from vapor exposure. In case Lovecraft...
You might get more help if you specify the coin type, or better yet provide photos.
Depends on all sorts of things. Sometimes, oblique lighting (exaggerating relief on all the coin's features) will help. Sometimes magnification...
I'm picturing a big old view camera, on a tripod taller than me, looming over a tiny coin...
When I was learning to shoot DSLR (with a Digital Rebel, no X-anything, the original 300D), I saw lots of advice to overexpose slightly when...
Hmm... very cool, but I'd be completely in the doghouse if I brought 24 more containers into the house. :rolleyes:
I probably wouldn't. Blow dryers blow unfiltered air, so they're slinging any dust in the air against your coin. Since the coin's damp, the dust...
It's great that you noticed this, and it's important to learn from it. Here's the lesson: when you look at a random pattern, your brain is really...
It could be gold-plated, or stained, or environmentally damaged. Can you show pictures of it next to a normal-colored quarter? (It's always hard...
...but the legislators responsible for signing the new composition into law stayed bought, and we're stuck with this composition, even though it...
Osmium's a really weird one. Super-hard, super-dense, super-high melting point, super-low vapor pressure, and super-unreactive -- except, for some...
In fact, if I'm not mistaken, most 1982 cents were struck in copper -- the switch to zinc came fairly late in the year. There's no premium for...
From previous discussions here, I gather that those manila envelopes from the early 60s weren't actually sealed from the Mint, so a "sealed...
Separate names with a comma.
