The Incident, one of my favorites, is no longer for physical sale though you can buy it digitally. You can get face value or above in the right market.
Battle Kid sold huge numbers and was available for a long time. I don't think it is currently for sale, so you can probably get similar to the above.
Lizard is still available, but you have the Kickstarter LE version, so I would say you can still get good money for that one.
Swords and Runes is still available for sale.
American Dream, B-Wings, Road Fighter, Portopia Serial Murder, Samurai Pizza Cats... IMO no longer have a large market, I think overall buyers have moved away from limited editions of pirate NES releases of Famicom games. I could be wrong though.
