It's tough to give a price estimate. No recent sales. It would be easier if you knew what he paid for them and offer 25% more as your opening shot. All I can tell you for sure is that if the stock is real wood, that's going to be worth significantly more. Also, if he has the original boxes, that too will bump up the price. Good luck. If he wants more than you are willing to pay, please let me know what he's asking and put me in touch with him. I'm not saying I'll out bid you, but if the price is right, I'd like to take a shot at it. I'll take good care of it.
Oh, it's Rosebox, not Rosebud.
