"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 investment. What do you think?"

I agree, but how do we know they were actually destroyed?
