  1. The thing I can't get past with EBay comps is how seemingly easy it would be to manipulate value. A few well placed Buy It Now's, where you end up buying it yourself under a different account, could significantly increase an issues value with a small investment in the EBay fee. A handful of manipulations is all you'd need because there isn't enough volume on any one book to factor it out completely. I recently saw the $5 blank, white cover of Hulk #1 jump up to something like $50+ on CovrPrice (which appears to only calculate FMV by EBay comps) due to a single $135+ EBay sale of that cover. That sale could NOT have been legit. In that case it was so egregious that it looks like they factored that outlier out, but it got me thinking how easy it would be to do it and how untrustworthy comps can be. Seems to me, price guides give a bit more of a sanity check on outrageous and unjustified market swings. JMHO
