I sold my Shiny Sableye a few weeks ago for 5.5 milions. It also had basically no market, I don't know if it was due to the game being almost dead though. Maybe holding onto it should have been better as there will be a player/money influx with Gen 5 update.
Right now I'm trying to sell a Shiny Golem, how much do you guys think it's worth?
I would also like some advice about this particular Charmander (F Charmander lv1 - Brave - 11/21/31/31/31/30) which I don't know how to price as I'm quite ignorant on breeding costs.
