Different people's "whiles" are worth different amounts. Some people are happy to pocket a $100 profit, and some people can't be bothered for...
Yeah, I'm thinking of the "Christmas tree" demo where you hang a copper-wire form in the solution and silver crystals grow on the wires.
I'm sure if you timed it right you'd get a nice layer of silver as copper displaced it. (Well, probably not a nice layer, more of a mossy layer...

All I did was a quick Google search, and Comsol was the site that provided the first result. So, busted, I guess. :rolleyes: If I get some time...
And that still leaves open the question (from another thread) of whether luster makes it through the copper layer to the zinc. My bet is that it...
Nitric or sulfuric acid definitely won't leave the zinc. It looks like the Mathers and Martin method uses sodium polysulfide, which you make from...
Not so much. Zinc is a lot more reactive than copper, and it's tough to find something that will take off the copper without immediately attacking...
This. Plating a cent that way will make it look silver, and won't alter its weight enough to measure with home equipment. I don't know what that...
What kind of conductivity test? Probing it with an ohmmeter isn't going to tell you anything useful, and all a Sigma machine is good for is...
Coins that were returned as counterfeit, then later acknowledged as errors? I've never heard of that happening. Can you show some examples? Any...
Mime variety? :rolleyes:
What's the issue? Some quick Googling shows that the 1955-D FS-101 variety displays relatively subtle doubling, and is an entirely different thing...
People will counterfeit anything. Even common Lincoln cents. The one you posted looks bad enough that it might have been someone just playing...
Wonder who the buyer was? If I were a billionaire, I might've been tempted to join the bidding war on something like this.
Absolutely. Even at local shows it's often easy to buy 40% at or slightly below spot.
Not even my parents. But people who were alive at the time reported the reaction, and some of us oldsters remember how to read.
Well, for common dates like this one, anyhow. Better dates and other rarities can still trade high even if they're damaged.
Solder is more likely.
Sounds quite similar to some of the criticisms when the original Peace Dollar design was first unveiled. :) You made me go back and look at the...
