His name is above.

"so I know who to look out for?"

No need to look out for anyone. I believe most of the chips are dispursed throughout the hobby. Its been 6 years since the Arrington fiasco.
Rare, no. Nice chips and scarce, yes. A lot of history, yes.

Only 300 collectors can have the 2 hot stamps. That would be true only if Roy had the whole rack from the CC. I do not know the exact amount of chips he had.
