It depends on the maker, but with some makers it's so common that it has little impact. A lot of Champions glow to some extent be it the ribbons or base glass, ditto Jabo.
The two on the right might be the newer (early 70's onwards) 'Bumblebees' - Marble King produced most of the old two colour marbles as black with a slash of colour.
Welcome. As Steph say's a nice mix. Some nice Vitro's in there. If you want to post them individually in the id thread you should be able to resize photos in most image editing programs.
Interesting - size wise would point more to Alley for me. I've yet to come across a Champion under 17/32" that's not been a solid or clear. It's possibly just what reaches me (I'm stuck with ebay/etsy rather than shows on this side of the pond).
They look like Classics rather than the investor runs - 1993-2007 ish. Identifying the different classic runs isn't easy. Some are pictured on the WVMC site.
Welcome - you should have a 'resize' option on your photo editor - if you use that you won't need to crop so severely to get the files small enough to upload. I don't think they're European or Akro, from the close ups though.
