"None of these has a grade on it and the chips contained are recent low-value chips."

Thats simply not true.
Our friend from the LV Pawn Shop had quite a few rarer chips slabbed. He had them in his showcese at the Trop Convention. I saw them in his store. Cutler bought a slabbed Z chip and cracked it while taking it out of the slab. He then signed onto the slabfree pledge.
