St. Mary's Alley IMO.

Lol Chad, I know the feeling. We all do.

Not really but sort of. There isn't really an ear shape that I see, but you can see the tendency of the glass pulling to the center of the marble which, often in combination with a shorter stream fold, tends to make the ear pattern. Same concept as what makes the buttcrack pattern on a JABO but Heaton had a bit longer stream so the ingot curled around more making an ear shape instead of flat on itself making the buttcrack (which Heatons can do sometimes anyway). Same reason Cairo has the "C" shape so often.

Heaton here.

You'll do better using Joemarbles, this site we're on now, Allaboutmarbles, and the West Virginia Marble Collectors Club pics for accurately identified marble pics. Lots to learn from the Archive sections of these forums and Steph's Study Hall.

DAS, JABO, or SMM. Leaning DAS.

A lot of the information on that site is incorrect. Yours is a Ravenswood.

It's a process, keep trying. It will start to click and the rewards of it will come.

Happy to help you out Dave! Glad to see you sticking with it!

The only one in that group I would call JABO is the green/orange one, 4th in the top row.

I'd go master, then two JABOs or Vacors. I can't zoom in and get enough clarity to be certain.

I'd stick with Master for the first, the second is a Vacor swirl. Notice it's not the same in any way other than color when compared to the MK bumblebees. Look at the construction and you can see the difference between a patch type marble and a swirl. MK wasn't in the swirl business. Last one also looks like a Vacor. Vacor makes both swirls and patches and other types too.

Yep, same here.

From these pics I'd call the first one Ravenswood. Then you have a brick normally attributed to Akro, and a red/white Alley, and the dark one looks like probably a Ravenswood of some sort, nice well lit clear pics of it and the first marble would be nice, the first is a good marble.

Yes, that is a known Kokomo type. Here's' one

First one yes, second one no.

Looks like a transitional.

Kokomo

The makers had sections the marbles rolled down. If the marble fell between the 1/2" track, it was a 1/2" or maybe reject, if it fell through the 5/8" track, it was a 5/8" marble even though it might have been a bit less. If it didn't, it would go to the 11/16 or 3/4" slot, whichever they had set up, and it would fall through it and be called that size. A .66 marble would have gone to the 11/16" or 3/4" track most likely. Some makers even used the ought system, like double ought (00), and so on. They weren't so precise as we are now with these calipers.

Akro to me.

Yes, St. Mary's Alleys.

Good example to compare with Chad. I agree, th OP doesn't look like mica.
