Ten cents to twenty five cents.

I think they are all modern Jabo's.

Size makes a difference.

The top left is either Alley or Jabo. Need more or better views to know for sure. The top right looks like Jabo. I agree the bottom two are newer modern handmade torch made marbles.

Common Vitro Conqueror. No oxblood.

I agree with all. Not MK, probably Vitro but chance of Akro ?

Top left Cairo. The rest are Ravenswood.

The flames sure look Alley, and a possible Alley. But Akro did different white bases with Milky Oxbloods. I have seen a few Milky oxbloods flame some, but not many as nice like this one. Plus the factor of trying to convince people that it could be Alley. So your best option is to put it with Akro.

Christensen Agate.

Akro - Vitro - Imperial - Maybe Jabo - MK - Master

Akro - Alley - Jabo

Not much to go on.

I would say torch made.

Ravenswood

Most collectors think a Akro Carnelian should glow under black light. If Cairo it may glow or not glow. I am sure it is Cairo. Most if not all Akro Carnelian's contain white. Some people call the orange oxblood a Carnelian. Most of those do not contain white and most do not glow. So many do not consider those orange and oxblood as Carnelians. Here is link to a box or Akro Carnelian's. Easier than taking pictures of my box. I do not think your marble looks like these in the box. We all would like our marble to be some better than most actually are. But, it is what it is. It is your marble, you may place it or label it what ever you like. Just my opinion, is for Cairo. https://www.ebay.com/itm/vintage-Akro-Agate-carnelians-marbles-in-original-box/153383499613?hash=item23b65e775d:g:UH4AAOSw5e5cah19

Cairo Novelty. Many Cairo have the not so good seedy base glass and weak colors. Plus many Cairo glow under black light.

Vitro Helmets look like a football helmet. A opaque white helmet with a stripe near the center and a face opening.

Probably a roll mark. If the hot glass glob is to large for the groove in the rolls. The marble will not spin correct. The excess glass will push out to a point. A round circle or crease will be formed in the hot glass, where the over size marble rolled around on the edge of the roll flight or top edge of the groove. The marble should spin in all different directions in each groove. If over size it will only spin in one direction and it makes a round crease or mark. Then the excess hot glass is pushed out to a point, or nub. If the glass is a little cold, that will also cause a wrong spin and a crease or roll mark. There are probably 100 things that can cause roll marks. Making 200-300 per minute, a few every ten minutes with roll marks is normal operation.

Left is Vitro Conqueror. Vitro All Red has a red patch on one pole, and a different color patch, other than red, on the opposite pole.

Probably a machine roll mark. If a chip it will be dipped in, sharp around the edge . Chip is missing glass. Roll mark is as made crease in glass.

I agree Master Alley made at St. Marys Marble King All plain and very common. Keep hunting !

Vitro All Red Vitro Tiger Eye Can only see one cut so, I would guess Akro patch.

Maybe jorkscrew ? Can you tell if it older or newer looking glass ? If old lazy Akro cork. Second one(dark purple)is either Ravenswood or Champion, kind of generic. The third(blue)one is Cairo Novelty.

Just Rainbo.

Correct and two color for me. Some call it a Horseshoe Cage Cat Eye. See 5 & 7 pictures. Most likely made at Anacortes WA.
