not so fast. ;) Those are the three sale prices. Two of them were buy it nows, so we don't really know how high those two buyers were willing to really go.
Consider this, how many people out there really failed to cash in these chips? I bet very very few. It makes you wonder, in 10, 20, 30 years, this is going to be a first issue chip that hardly nobody has. There is also little to no chance of ever seeing obsolete released out into the public since vegas now destroys them.
I bet these are a fairly smart invesment. What do you think?
