I think these are both Cat's Eyes, maybe foreign. The white inclusion you see is a piece of oven brick. And bananas are usually associated with the Peltier marble company, and I do not believe either of these are Peltiers.
The first looks like a newer confetti style marble. The second is an old German cane-cut hand-made, an Indian I believe. The third falls among marbles known as West Virginia Swirls. It may be Alley or Ravenswood. The last one is interesting but I would need more pics to tell what it might be.
No, this is a Black Line All Red. The most common Blackies have the same color on both poles, with a (usually) much thicker black band around the middle.
His description of cracking and fragmenting grinding stones is pretty harrowing. I hadn't thought about that before but I sure wouldn't want to anywhere around when it happened - yikes!
Carrying fossilized poop around is a little different than carrying marbles but I can see why you would if it's from your Grandfather.
