Unfortunately not knowing the price really isn't within the scope of the trading ground rules. No 'bidding' is the rule, to avoid any kind of bidding war. Even if you give worst case pricing (as negotiating a better price is normal) its better you put something solid down. My suggestion, based on current condition, base your prices around original price.
