To Sell A Player Collection???

I think I stated before that I used to collect Marino cards.  I stopped long ago.  Somebody contacted me to see if I would trade or sell them.  Since they have been just sitting in a box for over 10 years I am actually contemplating it.  Has anyone ever sold a large PC before?  How did you justify it?  How much do you regret it? 

I also don't know what to charge for them.  I have 358 different Marino's all in top loaders.  Some are inserts some are not.  I know I could never get out of them even close to what I have in them but I don't know what to take for them either.  Anyone have an idea how much it may be worth?
