The one at the bottom is a patch type imho--maybe a PPP or "Peltier Peerless Patch".
One image? hmmm?
These marbles could all be flat on the other side---just sayin.
Marble--On!!
I love that chunk of crud in it--pretty cool find.
Does that crud invlove any sparkles?
It is a Peltier, so you never know unless you ask.
@Fire1981 would love this one too.
Marble--On!!
Veiligglas produced plenty of opaque marbles Fire, they are pretty cool to look at.
I think that I stole an image from somewhere, Much thanks to who-ever--great image!
Here it is Fire.
Marble--On!!
At first, I thought that this may be a Veiligglas marble.
I can see where Ric is coming from though.
Regardless--it is a nice find.
Lets call in @Mojo for an opinion and @cheese as well.
@Chad G. also know these types.
Marble--On!!
With the new information that @shiroaiko has provided--lets call her in.
@Mojo is on top of this type as well.
Most look Dutch to me.
I question the lower left and the one to the north east of it.
Nice group!
Marble--On!!
Your images here show a "coke bottle" type transparent glass.
If it is crystal clear--MK if not--Asian.
Almost all Asian Marble used recycled glass--thus the coke bottle effect in the transparent.
Marble--On!!
