I will say this; you did a great job of sorting these.
The first image I am quite sure are Vacor (from Mexico) âBlack Panthersâ. 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 patchâthe lower right is a Vitro Conqueror.
The ones to the right may be Vacor or one of many other makersâthe dark metallic ones.
Keep them comingâI love to do IDâs---we all do!!
All opinions are welcomed and appreciated.
MarbleâOn!!
