It's actually from a chemistry classroom. You drop the penny into some sort of solution and it grows copper crystals over the course of a few days.

Cool token!
My focus is coins.
My inclination would be to try washing the Nepotian first, in a distilled water bath. I've purchased a few doctored coins (knowingly, and for...
My understanding is basic, so take it with a grain of salt. A bona fide patina, in the way collectors of ancients use the term, is a layer of...
Just a fantasy piece. Athena on one side, bow and club on reverse, but the lettering is gibberish. I've seen this particular inset in other jewelry.

I have no way of proving it, but I believe desert repatination started with Middle Eastern dealers, particularly dealers in Judaean coins because...
Yeah. We've had our fill of that, lol.
I like both coins very much, but keep an eye on the Domitian - it has a few holes in the patina that could grow bronze disease. That being said, I...
Come on in, the water is fine. As to budget, many ancients are far less expensive than US Classics. The first coin I posted cost $20, the second, $40.
Perhaps you guys use the word patina differently. We only use it to refer to mineral deposits that have accrued evenly over the surface of a...
I misunderstood you then - you were speaking of IHC's. IHC's haven't had enough time to develop a true patina, so of course you're correct....
Are we talking about the same thing? Collectors of ancients find an attractive patina highly desirable. Stripping an ancient coin of its patina is...
Green spots on an IHC are likely bronze disease. The sort of patinas you find on ancient bronze take centuries to develop, perhaps at least a...
I don't think you surf bad porn.
Separate names with a comma.
