What can I sell these 3ds games for?

Having trouble figuring out a competitive price without giving them away. All are excellent and complete.
Fire emblem awakening
Star fox 64 3ds
Project x zone
Kid Icarus uprising
Bravely default

Any feedback helps, thanks

All of those should be pretty easy to sell for moderate prices, with the exception of Project X Zone, and maybe Kid Icarus.

Project x Zone and Kid Icarus will be hit or miss for the most part, but everything else should be an easy sell for around the $35-$45 range, which is about where the market is for those.
