I will say this; you did a great job of sorting these.
The first image I am quite sure are Vacor (from Mexico) āBlack Panthersā. These will show up in a variety of colors with a black base.
The second image shows some vintage marbles- the middle ones.
The top left is an Akro Agate patchāthe lower right is a Vitro Conqueror.
The ones to the right may be Vacor or one of many other makersāthe dark metallic ones.
Keep them comingāI love to do IDās---we all do!!
All opinions are welcomed and appreciated.
MarbleāOn!!
