I'm not sure about the Jok erz chip, but I don't think it's a drop chip. It would most likely be more beat up.
I did run into a lady who has some Winner's Circle chips. Older/newer I don't know. I never saw them, but she says she has plenty. I did tell her about the ChipBoard. Maybe she will find us and post. I would hate to see them sitting in a storage locker forever. She seams to be a very nice lady.
