Sorry I wasn't around CJ stores in those days.
"it is likely that more of them exist'

Why wouldn't it be likely? Do you think they made 2 and stopped?
No haven't seem them, don't have them, ruling out nuttin. I do have the 10¢ out of what appears to be the same run.

CJ's are like arrowdies, if someone finds a bunch they bleed them out high, then dump them on the market. I usually wait for the dump.
