The next time you advertise an auction, please be truthful about what you are selling.
Sorry for the confusion. I wanted to get a start on the auction and thought they would be in my possession the following day. My bad.
I actually have them now. Please see the following pictures.
So I guess you were counting on someone telling you how to do that right?
Well as far as I know it was sad at the start that you will know grade but that was retreated at the later date... But you can look at chips to see if there are any markings on it. But be really careful. They are really sensitive since that is silicon slice on top. Static can kill it. If you don't know how I would suggest not to touch them. Juts do visual inspection. I don't know how they are packed so I can't tell you much. But if you really need to touch them do it when you are holding something that is grounded and use a tweezers... But don't touch silicon... Be really careful...
They are not demarcated with grades as you stated. Further, the packing seems a little spare to be honest.
I'll be re-posting the auction for anyone interested.
