I've done a quick search around Ebay and have come up with the following, this is only provided that the gameboxes and manuals are with each game and in reasonable-very good condition. Bare in mind prices are approximate, based on what is currently listed and I'm not in the US so I've listed these in AUD and shipping internationally or otherwise I've not included:
CVC - 100 +
COTM - 50
HOD - 90 +
AOS - Over 130/140. (The issue is the Double Pack HOD/AOS which collectors may opt for instead; around 110 AUD)
DOS - 50 (Still Available new on Ebay for a bit less, but it's not easy to come by new)
DXC - 35
CV (GBA Classics) - Approx 100 +
POR - 30 (still available new for 39.95 from Gamesmen.com.au)
OOE - 25ish (Just bought one the other day New for 32 AUD delivered from Canada on Ebay)
As for the rest I'm not 100%, smash Ebay if in doubt.
The next thing is whether you want to make bank, whether or not it's hard for you to part with these games etc.
If you want top dollar I'd suggest going through Ebay or instagram to avoid paying commission.
Also if you're really just wanting to clear your collection out then it's probably no good selling anything to me as I generally find offers where shipping is minimal on Ebay (or other) and I don't live in the US or Canada.
Also I don't know you, but as a fellow Dungeonite I'll offer my advice, don't sell anything that's rare or worth a lot now. Because the market for collectibles is actually quite good but the economy is quite bad at the moment, I'd be inclined to keep your super-rare games for when people are actually hungry to collect and are collecting more competitively. For now people are just trying to pay the bills. Just friendly advice, take it or leave it.
