Great Vintage system - need help!

[Dutch22]

I have a system that includes a pair of RT12s, CS250 for center, PSW300 and a pair of M5s in the rear. Problem is that we moved and now this system completely overpowers the smaller family room both acoustically and visually (per my boss) so I need to get a new set of (smaller) Polks - there is always an upside! How can I get an idea as to how much my present speakers are worth? I know how much I paid but how much can I reasonably expect to ask for them? Thanks for the help!!

RT12? not ringing a bell with me, but many others here are far more knowlegable than me. might want to try to get a picture of these in case they dont ring a bell to anyone else. post the pic here and see if anyone can help.

Here is Orion Blue Book value for a reference. I would personally not expect much above Wholesale Mint as those speakers aren't rare. That would also mean that they are in fact MINT :)

If you wish to sell them here, pics are a must. You will enjoy picking up some new speakers anyhow, be happy ;) Good luck.
