I believe its After-Market worth is at least $1500-ish right now.
That is based off of a recent sale of Casino24.tv selling for something like $1500, and I definitely believe yours is better!
I own VirtualCasino.tv and I won't let it go for any less than $250 today, so you got that going for ya but For a quick sale here at NP, I believe you could prob get between $250 and $500.
