I'm not sure what your point is.  For that price you could buy a lot of different things, but I don't see how the value of GPK final art correlates to the graded set.  I've owned some of the final art pieces, but they're boring because they're small so they don't display well and they haven't appreciated the way graded cards have.  Other than the fact that they are both items related to GPK there's no correlation.  Bottom line is that it's easy for anyone who is interested in this set and looking to come up with a reasonable offer to go to completed sales on eBay and look at what the individual cards sell for.  You won't find all 176 of them, but if you extrapolate based on the prices of others with similar populations and add them up you'll get to between $125k-$150k.  I've been offered $100k by a dealer who intends to break it down and sell it for profit.  So it's going to take more than your substance-less jab to convince me that my asking price isn't completely reasonable.  I've been collecting these for a long time and I'm well educated on this, admittedly niche, market. 

Now, if its Pound art you like, I have a custom painted and signed Nasty Nick card that is almost final art level which I'll gladly sell you for .5 BTC.
