Welcome Melissa ! Some cat's eyes are good! according what you might have?! To me every marbles is desirable! I see Vitro's. (Marble King, i = Bumble bee's ) Peltier rainbo's, Alley's /These are good learning marbles, I wouldn't throw any out! There is a lot of good information on this site dig around in the archives Steph's Study is good place to start They are very helpful here. It's hard to tell what you might really have unless you take all 4 sides of the marble they will need to see the seams / also if you just post maybe 4 at a time would help! view how others post in marble I.D's for examples Have a great time wish I could help out more. Happy Holidays!
