Tesla's oscillator Given all Tesla accomplished, it's easy to imagine that he couldn't exaggerate -- but in this case, I'm pretty sure he did....
Well, that's the rarest variety I'm likely to see this year -- the 1982-D, small date, bronze planchet, "No-D" cent!
Can I turn on subtitles here?
Can you summarize? I can't load the page, it's hanging forever trying to connect to a website-analytics service. :( Edit: never mind, got it to...
How else are you going to take run-of-the-mill quarters and sell them for a few dollars each to magazine and newspaper readers -- sorry, that's my...
I knew that was a thing, but I didn't know you could use it to deposit coins. I'll have to look into this...
That one's got mine beat for sure, and I thought mine was hammered (by 1921 standards)... [IMG] [IMG]
It's better than that. If you blow up the super-mirror shots, you'll see that the detail on the devices is fuzzy, but the borders between the...

The laser "frosting" (pockmarks) they use today obliterates fine detail. There was a thread a couple of years ago lamenting its effect on...
I'm seeing $70 over face, $1387 and change with spot at 1318?
DULL AND UGLY, duller than the Barber design. I have the greatest admiration for Franklin himself, but not that coin design. Ick. Well, I guess...
Pretty sure 12 million in Monopoly bills would be worth a good bit more than a run of the mill 1913 counterfeit. A lot harder to carry, too. Oh,...
Well, that info at least gives a weight to compare to -- but I'd do a magnet check before anything else. I'm afraid those denticles look like...
Based on what we're seeing from AI practice (not "research"), I'm not convinced of that. Sure, any AI system will produce judgements that a human...
That used to be a lot of space. :)
