I disagree totally:
While more difficult to sell (I don't think that is in dispute) because you need a more specialized collector for them. The cheapest any of these cards will ever sell for on EBay is $1 and there is a premium for better players.
I think if you start a lot like this at $395.99 in an EBay auction with the cool picture you might get some interesting offers because of the bulk. Individual player collectors would be very happy to add these to their collection. Here are EBay completed sales listings
