Polk Audio - RT3's pair - M Series - M1's pair - CS101 - single center Speakers

I just came across a box in the attic appears to be never opened, inside are the RT3's a pair, and the center CS101 with the M-series pair as well, can anyone tell me if these all are worth anything? are they hard to get rid of, are they sought after? if someone could help me would be greatly appreciated. I am new to this website
I cannot locate anything on eBay that is as these are

I see RT3s in great shape on eBay frequently. I bought a pair (that I love!) last May for $80 shipped. They certainly won't be hard to get rid of....

Obvious troll is obvious.
