Yup, the rest of it is green goop somewhere.
Vinegar is most certainly an acid. Throw in hydrogen peroxide, and it's an oxidizing acidic environment. Even a copper cent would've been etched....
Bleach and acid is a popular combination for dissolving gold out of ores. (It gives off lots of chlorine gas, for the bad-idea cherry-on-top.)...
Not until you get up to MS. If you were going to be adding a MM, you'd want the O, which apparently goes for about 10X the P price.
I guess the operator wouldn't say "yeah, we have people with million-dollar tables all the time, and just getting your neighbor to keep an eye on...
See above. Bleach is basically alkaline salt water with extra chlorine dissolved in it. Salt is terrible for most metals; free chlorine is worse....
Makes sense. Of course, we can't be sure that both strikes are from the same die without seeing the entire coin. :troll: I mean, there might be...
Point of order: how can you have a "Double struck" that isn't "Overstruck"?

A bit over-overstruck there?
Bleach is great for breaking up organic stuff -- it's alkaline, which breaks down fats and proteins, and it's an oxidizer, which kills things and...
It's never too late to put gold plating on a coin. I've got a bunch of gold-plated Liberty nickels -- one or two are detailed 1883s, most are...
Dude. Be kind.
Especially when the "marker" is an image edit. ;)
Who in the world would suggest using bleach on silver?
Okay, a solvent, like distilled water or xylene or acetone, WILL NOT do that over the space of a day or two. An acid certainly will. So will...
@desertgem has posted photomicrographs of Morgan and Peace surfaces. Their texture is different, giving rise to different luster, and different...
Okay, suppose we agree that this is bad. What is the Mint supposed to do about it? How is the Mint supposed to guarantee that the coins you buy...
This slides in an assumption that most Mint buyers are speculators, interested in coins only (or mainly) as a way to make money. I was going to...
Sounds like someone had read Arthur C. Clarke's "History Lesson". :rolleyes:
Separate names with a comma.
