I can't begin to address your points about the ancient market, but I'm a little confused by how you started with "I used to sell on eBay and my...
To be fair, I don't think looking at the last 12 months' performance constitutes "cherrypicking" -- just a bit of (hopefully temporary)...
Heh. When I was just a little chemistry-set enthusiast, I used to check out chemistry books for kids from the library. It was an old library, and...
No, that would be the site where people were asking whether the poster was planning to drink acetone, and he explained that he was only using it...
Well, if that's a fruitful approach, it means that I'm wrong, and the PMs do get depleted (expelled) during the normal life of a catalytic...
I first came across complex numbers in the early 1970s, and the only symbol I ever saw used to mark the imaginary component was i. It might have...

Platinum and palladium come close, though. If a car needs a replacement catalytic converter, it's because the old one wore out or got damaged --...
In June 2008, rhodium hit $10050 per ounce. (No, I did not type an extra digit by mistake.) In November 2008, rhodium hit $1000 per ounce. (No, I...
Huh. I didn't know acetone required that. Makes sense, I suppose. Fortunately it doesn't look like something that would affect metal or toning,...
I haven't looked closely, but I didn't think you could get 100% pure acetone there, only "nail polish remover" with scents and whatnot added...
I'd have to say Shield Cent, but only because they're saddled with the zinc reverse-galvanic-protection composition. I actually like the shield...
OMG -- The Sticker King!!! (29957blue, aka "Zack's", used to post photos of coins in 2x2s covered with stickers. The one I remember is "Less than...
I wonder how much of this is actually driven by large-scale coin-roll hunting (or, as some banks apparently call it, "mining"). If a bank has...
I use them regularly, too. I believe they behave exactly the same as a "regular" credit card number for the merchant, but I'm not certain about that.
Yep, that's got it! Thanks!
Oh, dear, it looks like maybe you were trying to link to images in a Gmail message. Can you download the images to your computer, then use...
So, will you be taking photo gear? I've got a 100-400L that produces an image of the lunar disc maybe 800 pixels wide on my sensor; trying to...
Taking them even further from their "original condition". ;) Seriously, I think the "removing foreign material" bit is necessary and sufficient....
Closer, but "contamination" is overly specific, I think. I still don't think "original state" belongs. The carrot was covered with dirt from the...
Separate names with a comma.
