Are these the same?

Thanks! All 6?

Jabo/Fenton Green Aventurine Swirl? These are four different marbles. 

Christensen Mustard Yellow Swirl? They glow a bit with a black light. Some of the swirls turn pink-ish. These are individual marbles designated by the size photos. 

Any help would be great!

Thanks! First time i've heard of lattacino cores. Makes sense when looking them up. I assume these are Onionskin?

Last one, I promise!

I think these are all German Onionskin. They aren't in the best shape, but that is the downfall of being the coolest and heaviest in my collection!

I love this little guy! Can you guys help me identify it?

Thanks! On to the next.  

My Grandfather was in the Army and based in Germany. Is this a hard to find marble? Can you estimate the value?

It feels like porcelain. What else can I provide.
