I was expecting this card to sell for at least $200 as well.
The interest in Randy Savage cards has really not been shown to be that large. His cards moved up quick when he passed away and then faded pretty quickly.
As was mentioned earlier in the thread the centering on this particular example was not as strong as many would have hoped for out of a PSA 10 and I would suspect that hurt the price as well.
And finally my example was no longer a Pop 1 and in many cases the second card to hit the pop report brings a lower price then what the first would have.
