$10.oo era un ottimo prezzo IMO

I agree

From the second photo, it looks like an "ultras" run but I'm not sure

X2

No ox here

These in question shouldn't be reproductions in my opinion, as they don't have much value, so it wouldn't make sense to reproduce them.

Some may be, but not these

Yes,  Vitro
The fourth photo almost threw me into pelt.... huuu

X 2  Very nice!

The main ones would be (in my opinion) Heaton or Cairo but nothing for sure, unless they come from excavations

Beautiful marble Jeremy, but not cac for me

Looks like an old MK to me

Correct!

Pelt

Vacor recent "hurricane"

 A CAC like this would be true black with bright snow white swirl and smooth slick surface.  

That's how it should be!

Sembra un mix di Marble King e Vitro's...

Yes

You are welcome

White base, the S is not thought out, I have no idea of the manufacturer

I'm not sure if you fall into that category, but I don't think so, as that pinkish or orange brown seems to be more pronounced than a "sweet potato"

Vitro for me

Crystalline glass
