post with you. Dont make ridiculous comaprisons between cardboard flips and the plastic holders being discussed. When these 'slabs' first appeared, someone contacted the grading company and found out that slabs containing more than one item are not graded. We also got confirmation that the chips are thermostatically sealed. (the purpose being you cant swap the chip for another.

Now to answer a question you raised before, Steve Cutler, Tropicana Hall of Fame Museum curator, puchased a Z chip (possibly unique) in a slab. He opened the container to get the chip out. The chip broke in half. They are sealed in.

There are of course 'slabs' of different types and qualities, but this 'gold label' wrapped round the join is not the thing sealling it I assure you.

This is the reason so many of us are against slabbing.
