Not sure where or how to get knowledge

I have 8 neo geo arcade mvs full kits most pristine condition and matching serials I'm not looking for a fast sale but looking for help in and where to sell. I apologize right now if I shouldn't say this here or if I offended anyone. I just want to be directed to the correct location of this subject if possible. Thanks I'm also not a reseller in any way or means as well.
