Hello - I am a collector of sorts, although I haven’t purchased any yos in a while. I do have a number that I bought somewhere between 2001 and 2009, roughly, that I have no idea what they are. Pictures below, any help to identify would be appreciated. They are all metal, I assume aluminum.
Thanks to all. I’m pretty sure that none of them are Chinese knock-offs. This is like an episode of ‘Antiques Roadshow’. (holding hand to mouth)“Oh MY!! I had no idea they were worth so much!!” I really didn’t, but thank you for the information.
