Hi Jason,
No, I decided not to bid after all. When it was 99 cents, that was on
thing. But if my memory serves me correctly, last time I checked it was
about $22.
But has anyone heard of a Spanish collector named "Ceruda"? Sounds like the
beginning of some suspense movie!

Hello Mark,
I wouldn't be surprised in the least if the fellow already knew - I've
sent such messages before, only to meet a stone wall of silence, or a
vehement denial of the facts from a mineral dealer who knows less than
they think they do about rocks from space. That said, it could well
be an honest mistake. There's no telling.
It's worth a shot I suppose, but if I'm not mistaken, the auction
closes in about a minute, so it's a bit late for that.
Another one bites the dust...
Regards,
Jason

Hi Jason,
Thanks for the info. Looks like you're right.
I checked "Rocks from Space", and color plate IV has a picture of a Toluca
specimen with a closeup of ferric hydroxide and hydrochloric acid exuding
from between the Widmanstatten plates.
And it looks like some of those brown "crossed lines" on the ebay sample.
So what should I do - inform the ebay seller that he has a sick patient on
his hands that he is trying to unload? :)
Thanks again.

Hello Mark, All,
Those squiggly lines are what Nininger coined "lawrencite," a
corrosive "disease" that occurs primarily in the presence of
terrestrial salts. While the term is fairly well-recognized, it
generally applies to meteorites which experience accelerated oxidation
even years after having been found, having spent long periods of time
in unfavorable climates.
The slice does indeed look like Toluca, and it might be a fine
specimen if refinished, but good luck with preserving it - maybe Bill
Mason might have a word on this.
That said, there are no troilite inclusions visible in the slice.
Regards,
Jason

Mark, List,
It looks to me like an etched iron meteorite slice that has been clear
coated and is rusting. Corrosion will boil up and worm its way around
under
coatings. Some Toluca have prominent troilite. None is obvious in this
slice but it still could very well be a Toluca. Maybe someone read a
description somewhere that mentioned troilite, saw the Widmanstätten
pattern
and figured that is what the "crossed lines" are. You might pick it up
cheap, refinish it and pray.

Would be interested on any comments on this Toluca sample that I came
across
on ebay. According to the seller, the sample was purchased from a
collector
in Spain named "Ceruda" and the troilite is "the crossed lines on the
specimen."
