Andy suggested a "Slabbing Kit" where you slab your own chips, and put the grade you like. I think maybe EVERYONE should get a Slabbing Kit and slab their own.

Silly? Maybe, but just as valid! THE KEY here is NOT the value of the chip but the PERCIEVED value..... Remeber Beenie babies? (people PERCIEVED the value to be high and would continue to go higher)
Mark is trying (on eBay) to create the "illusion" that one Sacagawea Dollar is worth $100 MORE than another just like it. If he convinces someone then he wins. (Hope the buyer is one of those people who has an extra $50K lying around, like his investors)
