OT: Antique metals and a copper penny mystery |
I've been working lately on polishing up the various metal antiques I have, more
specifically a small coin collection - or what's left of it, anyways, after I
had to cannibalize it to make bus fare during a rather extended dry period a few
weeks ago. I've got two questions about it:
1. Someone once told me that clean and polished coins aren't as valuable as
coins that are left dirty. Is this true? If so, why?
2. I put a few pennies in a small puddle of "Tarn-X" tarnish remover and one of
them - just one - came out with an apparent "grain" across its surface. Just
like someone took a wire brush and scraped it in the same direction on both
sides of the coin. It looks almost like some sort of artifact of the minting
process, but I'm not sure - and none of the other pennies came out that way. It
was a 1958 wheat leaf penny minted in Denver. Anyone have any ideas why that
might have happened? I noticed that I had also put a 1942 mercury-head dime in
with it if it matters, and there were some pennies from various decades and so
I'm sure there was also zinc in the mix.
Just querious... :-)

Because it removes the surface. Keep doing it and detail disappears.

Ah, that I can understand, at least with actual polishing. Thanks! :-)
However, with something non-abrasive like Tarn-x - a liquid you simply have to
dip the metal in to get it clean - would that still be the case? Or does it
accomplish the cleaning the same way, just with much slower erosion of the
metal's surface? :-?

Some are supposed to be safe, but I don't know how they work. It's
been too many years since I collected that stuff. Sorry.
But thinking about it, there are two kinds of tarnish - oxide and
dirt. If you remove oxide you remove surface, and if you reduce the
oxide back to metal, it changes the surface.

old things look old, you know. I kind of like old things, and I expect
them to look old.
