Any Idea of what the new Rating (R-5, R-6) ect on the New finds on the Jessie Becks ERROR Chips?

I have been watching these very closely and I think probably less than 50 of each and maybe even closer to 30 of each have been found.

I'm sure by now that all the chips have been gone through, since they have been posted here and on ebay since a couple days after the original posting for sale.

Whats your thoughts????
