I haven't tried it, and I won't. But AGEs have copper alloyed in with the gold, and acids certainly do attack copper. As I understand it, you're...
You can buy a small digital scale that weighs to the hundredth of a gram for less than the cost of a single damaged Morgan. Get one of those, and...
Brass and copper are less dense than silver, but only by something like 15%. I've received correct-weight fakes that were the right diameter, but...
I'm surprised no other shop is willing to outbid that. When I was going to local coin shows, there were almost always at least a couple of...
I think that's vinyl flooring. I guess the idea is that "stains and spills" won't show up, but I'm not sure it's worth it. As for the Lucite...

Of course, if there is "economic collapse or that sort of thing", all those ETF shares would presumably vanish. Just like banks, dollars, and...
:eek:
I really, really want an XRF analyzer. But it would just be a hobby tool, and I wasn't raised to spend five figures on hobby tools. But if they...
No argument there. NOT a dealer who's going above and beyond to welcome a new customer.
I think you're being a bit unrealistic if you think G-F 1940-1962 quarters have "numismatic value" above melt. At least, I haven't bought them...
Shhh!
All excellent advice. I'll admit that I'm a bit cavalier when it comes to safety equipment if I'm dispensing from a dropper bottle, but for a...
