Sold Price Check :: 2 10' Precision Power Flat Piston Pro's

I keep hearing that these things are VERY RARE and hard to find now.. I'm actually going to be buying a set of 10's off of someone I know prob. pretty cheap and I'd like to re-sell for the full value. I know some people get into collecting the old car audio stuff.. so if you could just give me an idea of what these would be worth.. that would be great!

EDIT***

Here are some pics of what they subs will look like to give you an idea of what they are..hehe



 
I think those are the PC (powerclass version) instead of the Pro versions. The PC and Pro series look identical from the front; same cone, surround, but the PC version has a slightly different paper gasket where the true oldschool Pro series has a PPI logo'd rubber mounting gasket.

Now, the easiest way to tell is looking at the rear of the subwoofer. The PC is a cheap version with a stamped basket, weaker motor structure and small magnet. The Pro version has a massive cast frame, huge motor structure, gold spring terminals, and a large magnet. The PC subs aren't worth much at all, however; the Pro series were very nice subwoofers that were really only limited by their Xmax, but they sound fantastic just didn't have amounts of output like most SQL super-woofers have today.

Check the subwoofer out before you buy it, trust me, the cheaper and newer PC version isn't worth anywhere near the prices you see above. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Here is a photo of what a Pro series should look like:

First off, what is that soposed to mean?

I wasn't planning on selling them on here since most people just do trades or lowball.. and there is nothing wrong with the speakers themseleves.. they work perfectly..matter of fact I believe he had them in his car no more then 3 months ago and sounded great!
