Whoa, whoa, whoa, that's what I was forgetting :oops: -- when you heat the copper plating enough, the zinc underneath dissolves into it, forming...
You're right, it's not rocket science. It's hindsight. In hindsight, buying at $10000 or $1000 or $100 or $0.01 and hodling was brilliant. Buying...
A little acetone soak should clear that right up. ;)
So, what do we think? Half a million, given that individual CU64 notes get $3000 or more?
That is a lot of scratches in a little area -- an oddly specific area. But it might have been someone scraping away cruft to see if there was...
I don't think that's exposed zinc. I think it's chemically altered copper. You could test that by putting into water with some lye (drain cleaner)...
Okay, for that, I won't snark about PCGS putting anything you send them in plastic. I can imagine some internal debate about whether they could...
And, of course, those who sold into it, especially near the peak. Ah, to have sold a bunch of coins at those prices, and put the money into gold...
Thanks to this thread, I now know that "planchet roughness" is a thing that can exist on high-grade coins, and I have some idea of where to look...
I think you're saying "$100 in gold" when you mean "$20 in gold". $100 in gold would've been a bit less than five ounces.
You're right, of course. And reading further into the article, I see that some of their analyses did require removing small amounts of material (a...
Did you buy in because it "felt like" owning a desirable coin, or was it more because you had deep understanding of the coin market and that gave...
I like to think that everybody has their moral/ethical limits.
Thing is, the liquidity of any particular asset can vary over time. Like @MDO, I live in an area where housing is going insane -- Apple is opening...
Yeah, and notice the key phrase from that article -- completely nondestructive. You don't have to take any metal off the coin. You don't even have...
Yeah, when you try to return that, they get all particular about how much is left on the roll...
When the supermarket puts paper towels on sale for 15% off, do you return the ones you bought earlier at full price, or do you stock up? ;)
Zinc Pox.
Yeah, you could oxidize the copper without disturbing the zinc underneath. It would still be tricky, though, because once the zinc is exposed it...
That would be tricky. Copper melts at 1984 F; zinc boils at 1665 F. I found this out when I was focusing sunlight through a large lens onto a...
