You think 8,000 is a bit low, I think 14,000 for a starting bid is a bit high. No offense, I'd hate to think of what you'd consider to be a 'reasonable GIN'.
Also, could you lower the start to 12000? The lower the starting bid the more willing people are to bid on it. It's weird. I can have a $5 card start at 5000 credits and no one bid on it, while if i start it at 499 people will bid close to or over 5000. I guess it's a "bidding high" or something.
