Any Idea what these speakers are worth?

I purchased two 18" JBL subwoofers at a garage sale about 6 months ago (Model # 2245H) for about 20 bucks a piece.. I took them into orange county speaker to have them re foamed and coned so they are like new in their current state! I was just wondering if anyone has any idea what they are worth? I tried looking around online and came up with nothing :/ I guess there are not many of these out there! (haha how many people have double 18's sitting in their home theater lol?) Thank you all for any answer in advance.. and I will be keeping an eye on the question so if you ask me something I will respond in an additional info line! Thanks again!
