Good question. I go with the $7,000, personally (10% of net).
How come you guys are hung up on fraud?? I don't see anything wrong, the partners took a chance of the painting, they may or may not have suspected it was worth more. So what, if the church was happy with their $ 3200. So be it.
I wish I could go back to every deal I have ever made, and tell the other person, hey you sold what I sold you and you made some money on it, so I think you should split with me. Yeah right. get real, this happens every day. I am bidding on some old coins as we speak, and I hope to find a market for them and make some money.
