That looks neat! Anyway, try asking in the Pokemon TCG forum. I'm sure donvannj will be happy to help you. :) Though I can already tell you, that seems way too high for that binder. But I'm not 100% on that. Never seen one go for that much though. Anyway, just make sure you don't try to sell it here, as that's against the rules.
But yeah, this forum here is only for questions about the forum itself.
