Thank you - I know people who go crazy over these mistakes. I don't go crazy, but I like them, just as Chad says, for their historical value! However, if they are prized marbles (we know which ones), or not prized, but that include unique and particular features, I think the value can rise quite a bit. Then, the matter can be subjective. Some Cairo Novelty errors, from excavation, followed by Ravenswood and DAS

I think it is a real cornelian, since it is not very 'special,' but I have never researched these things

Personally no, unless they have truly intricate reasons, or yes, a chemically altered aspect. So, very few attract my attention. the first one that follows after the group has an opalescent appearance (labradorite), with beautiful bluish reflections

Today I am wearing this..

Akro - 1 inch

Akro, imho minimum value

I once found one here in Italy with a glass similar to this one. It was part of an imperial group.

Yes for the first two, I have a bit of doubt about the last one....seems imperial

Correct

If it weren't for the measurements being so large, I would (perhaps) have attributed this to a 'Peltier Boyce second run 2001' cat's eye, weak, but those only reach a maximum of 0.669 (17mm) or 0.708 (18mm) I think it's a European marble, (perhaps) made in France? They probably made similar marbles, but I'm just guessing... Some images of a type of 'Peltier Boyce second run 2001', with a coloration similar to the op

Not whispler, even though it might have a weak, similar structure. Also, I assure you it would have been much more bubbly than this.

Ahaha, I had never heard this term "belly button", strong! Thanks again, Chad, for confirming it

Thank you! I just wanted to point out that you can see a ring-shaped pontil, typical of Navarre.

This marble of about 0.708 inches (18mm), with obvious fire damage, I got some time ago from a guy who claimed to have found it in a junkyard. Now, it was claimed to be MFC, but nothing for sure, any opinions? Here is the boy's statement: "i dug this from an old land fill . Plymouth NH jul 2017 Approx 3-4 feet depth. Also pulled out a bunch of benningtons and mib shards. Land fill was from a massive fire burned 12 homes. Late 40s." "The soil composition wat predominantly ash/charcoal. Almost all the glass in this horizon was melted. I had to dig through this to get to the pre 1900 dump" I took some photos and videos,

No Vitro conqueror

Not imperial, In my opinion, they are both Akro

Vitro

With reference to the second photo, it could be Pelt, but I cannot say for sure here Let's see other opinions...

Ravenswood- That metallic could be an accidental deposit that occurred during production. It happens with many mibs
