One more time.
If you can not look at a CJ chip and tell it is a CJ chip, at once, then it is not a CJ chip.

I have a FQ's 25¢ CJ with the hot stamp all but gone. There is no doubt it is a CJ chip.

There is no big mystery in IDing a CJ shiney hat chip. Its almost like a CJ chip is white and any other hat and cane is black.
