Neither chocolate or oxblood.

Tiger Eye (mineral)

Its a transparent Wasp. These showed up in the late 1980s. They are from that period.

Its a very simple design to make. The technique is called "raking". Looks like they blew off annealing, but thats common when they are in a hurry. Its not really a pontil. Its a small diameter glass rod attachment.

Looks like a flop-over ingot.

Nice egg!

Those are 1990s new-ish MK. They were available in fair quantity, not really HTF at all.

They appear to be minimally buffed. "Buffed" is polished by hand with pontils remaining.

The motor source states that they haven't sold that motor (or an equivalent) since 2017.

The Popeye patches were factory discards. They are overwhelmingly in that color combination. I have seen an entire wood Army footlocker full of them for sale.

It is a modern machine-made, most likely from a Mexican company known as Vacor.

That appears reflective, not reactive.

Just noting that Memorial Day honors US military members who lost their lives in the military service of the nation.

Lest we forget:

Put me down for Vacor

Its way out of focus - but I think it may be a fried marble.

"It depends". But it does affect desirability and value. Be wary of people who sell using the description "As-made". These days its popularly used as an excuse for a condition problem... trying to infer that it is somehow less impactful on the marble's value. It isn't. And the increasingly popular use of the term to describe nicks and other damage as if it makes that damage anything less than it is - is simply BS. How would they know when damage occurred? In the end - that damage is simply what it is. Avoid such sellers.

Its rather dark (glass) but appears to be a modern Bumblebee.

That looks like oven brick. Machine-mades don't contain mica.

Looks vintage to me (and I tend to be conservative).

They are commons, the vast majority appear to be in rough condition. Some appear to have been slingshot ammo at some point. Those two qualities will make them unappealing to collectors.

Agree - Champion. Is that a trace of horsehair in there - or a contrast line between transparent and opaque?

By the way - this is what oxblood looks like:

There is a difference between "condescending" - and advice that will help quite a few people from mis-identifying marbles as buyers by seeing things that aren't there - often by projecting hopes upon them. This avoids disappointment and over-paying. I can't count how many times I've seen buyers buy a marble hoping it was a mica - to find out that its scattered oven brick. There are many, many more examples - such as damage quickly interpreted as a "pontil". Being capable of accurately identifying marbles is the biggest help to collectors in their journey. Moving away from the growing "I hope it is rare" trend is important IMO. With fewer people going to marble shows a few times each year, the opportunity to learn with marble in-hand has become much less common that it used to be. Marble show attendance is a way to factually learn at an accelerated pace with an immense sampling set. But now that has waned and people are struggling to learn only by looking at a photo - some of which are poorly focused and over-exposed.

No ox. I recommend that instead of hoping/looking for some thing you want in a marble - you look at a marble for what it is dispassionately. Otherwise its easy to see reds as oxblood, damage as pontils/transitionals or an odd flake as "aventurine" or lutz. And that will help you identify marbles accurately when you buy.
