[MsWright323]

I friend of mine who just passed away not to long gave me their collection of games and some consoles I don't really know what I'm looking but a couple were in a smaller box labeled "$$could maybe help you get out of a pinch$$" I looked up 4 of then and from what I understand they are worth quite a bit anyone know where I can get rid sell a couple of em?
Ps he was meticulous like white glove when it came to these thing not a scratch on anything

Why not try the marketplace on this forum? I see some people use it to sell, buy or trade stuff.
