This is not a CAC imho. I will consider Alley Agate though with a mention of Champion here. All opinions are welcomed and appreciated. Marble--On!!

Not "impossible" my marble collecting friend but quite a rewarding venture in my opinion. Start with this book "The World of Cat's Eye Marbles" by Elizabeth A. Kempski. Last that I checked, she is alive and well. She is also a cat's eye expert. Do not be afraid to contact her, she is very amicable. As far as Cats go on this board, @YasudaCollector and @shiroaiko are the best with Asian made marbles that you could find anywhere. Issue a PM or "personal message" to either one and I am sure that they will respond in good faith. The USA made Cat's Eye's, Cat Eye, Cats Eye's--etc, are recognized by all of us here @TheMarbleConnection. Give us your best images. Three or four at a time. Well cropped and nice and clear. Sizes are important as well. You do you and good luck in your research, many folks collect "Cats"--me included--I am partial to the ugly ones made by Master Glass. ( that is just me). Marble--On!!

I agree with all above, it does look like a stone marble. Hold a glass marble in one hand and this one in the other hand. Switch hands after a few whiles and check again. The stone will feel cooler than the glass. Also, lightly knock each other on your front tooth and compare it to other glass marbles. Your senses will pick up a difference. (no smell involved here-lol ) Now, for a final evaluation, backlight the original marble of this post with a small pen-light. If it is a stone "game played" marble it will show some hit marks that are not real evident in hand. I think that this one is glass—weird but that is my opinion. I respect all opinions and hope to see some more. Marble—On!!

"Tiger Eye" seems right here. @Melissa may know the type. Marble--On!!

Vitro--size is alway as factor in Marble ID. Marble--On!!

You have to get a cheap measuring device at the very least laero21. A few bucks for a plastic calipers will not bust you. Just go to the local hardware store and find one, post an image with it measuring the widest point and post it as such. I look forward to these images. Marble--On!!

Welcome back to "TheMarbleConnection", Jzoook6, We all look forward to your continued participation and you sharing your gained knowledge from over the years. I agree that many are "Peltier Rainbo's" but I have some doubts on a few here. I will call in @YasudaCollector and @shiroaiko for some further assesments on these. These deserve further assessment imho. Marble--On!!

Size is always important regarding marble ID's. Nuff said! This one is a very nice example of some sort of Vitro--maybe " Just a Patch" which they made many of. I have come across this type many times and have a hard time "naming" them other than "just killer". The size is an important factor here imho. (I am guessing around 1") Marble--On!!

I see the red. This is a "later Model" Vacor "Serpent " imho. Marble--On!!

Welcome charziD to "TheMarbleConnection". I think that you are wondering whether or not the orange-red one has a pontil. It does not—this is damage either from play or from a dig, a disregarded marble that the factory specs did not meet. I encourage you to backlight it and post some more images. You need to be more specific with your ask’s or requests. Cool knife handle! Nice share here. Marble—On!!

I would call them "Bullseyes" but @Steph and @Melissa would know better. I know this--it is a very nice pair of Vitro Agate marbles. Nice images--Nice marbles. Thanks for sharing them with us here @TheMarbleConnection. Marble--On!!

The second one is a Marble King imho. Marble--On!!

Good eye Roberto!

The size of the marble is an important factor in the ID of any marble. Given the text behind one of your images, I suspect 5/8" or so. Pink is a rare color when considering "Vintage" or older Marbles. I would consider another pair of makers here, Master and Akro. This is a tuff one for sure--nice share and ask. Marble--On!!

I agree with you and your statement. The German handmade marbles and the “Stone Agates” were the main competition at the time the glass marble industry started in the USA. Notice that many USA marble companies used the term "Agate" to describe their glass marbles. Good observation here— Nice “Master Made” as well. Thanks for sharing it along with your thoughts. Marble—On!!
