I'm not sure either, the seams and swirls look real funky for a pelt, the gunmetal blue color is a little off for one to. I'm 100 on the other one you posted as being a blue panda.
Please remove the ball bearing, every time the steel touches the glass marble it causes damage, just put it in another jar if ya want to keep it,. value is next to zero if anything at all. Yes they were packaged and sold as marbles years ago but they are ball bearings.
Fort a proper I.D. present them 3-4 at a time with a view of each end or seam and each side for a more accurate I.D. It might take longer but you'll know exactly what you have
