Again, this is mostly based on my experience with electronics. Heat sinks -- I think you'd be more likely to cause damage by clamping on the heat...
Solder has quite a lot of surface tension. That's why braided copper wire draws it up. Gravity won't do the trick -- even if you sling it off the...
Yeah, I actually signed up for My Choice so I could get the narrower delivery-window report on my Mint package. I wasn't entirely sure that we'd...
I really do appreciate that. :) But I can't claim completely noble motives in this particular instance. I wanted to take a chance on getting into...
Ooh, I'll have to spend some time at that site. :) I started looking around, and found that concentrated (28%) ammonia is easily available now...
Okay, I've found another reference that mentions etching silver, and even gold, with an iodine/potassium iodide solution. That caught me by...
Hmm. I see ammonia plus hydrogen peroxide listed as a silver etchant. That might be worth a try, although you'd have to make it up fresh each...
I've seen other posts about a silver date restorer that was available a long time ago (1960s?), but I haven't been able to track it down. I think...
...and here's the circular smear on the first one's obverse, lit from two different directions to show how its appearance shifts (a bit like...
Here's the big obverse smear on the fifth one. I used strong oblique light and stretched the contrast to bring out the (mis)feature. [ATTACH]
Here's the first one I opened (at the top of the overview). [ATTACH] [ATTACH] That little obverse smear below Y is part of the smearing I...
Oh, and another horn for the polylemma: I could put 'em up on eBay, but that would likely get me less of a premium than MCM, and expose me to...
Well, the Kennedys finally arrived Friday. They're pretty coins, to be sure, but all of them appear to have flaws, and I'm trying to decide what...
ANACS puts counterstamped coins in non-detail slabs?! I let go of a counterstamped Seated Lib half a while ago at melt -- to me, it was just a...
Meh, I've seen worse. :) Nice find! It's even a semi-key date -- 1999s still command a premium, although possibly not in this condition. (Lowball...
Once again, I wonder how they're making money after eBay/PayPal's cut.
It looks like that's getting on toward semiconductor grade, and I'd think people looking for metal at that purity might look only to known...
Ah, FedEx on 3 or more coins. That gives them a margin of, um, maybe 0.1%? Maybe what they're planning is to submit the ones that they're sure...
MCM appears to be offering these for sale at a wire price of 1357.73. How can they be buying at 1240 + 110 = 1350, plus shipping?
It's not just a grading racket, but a grading ratchet -- as long as you keep reconsidering/crossing it instead of cracking it out, it can only go...
Separate names with a comma.
