The oddball black $50 was found with the hub mold chips and also had yellow and white matching chips so I have to assume they are one and the same (minus the mold).
NOTE: These may or may not be the chips you receive, I'll pull randomly from what I have. I can tell you that they are all in the same condition and, if you choose, clean up very nicely.
