One of these sold for 10 or 15m on Napa the other day (Luna). There's a black one for only 8. 15 is reasonable but I would not pay it personally. 45 is wishful thinking only. Won't even get one palm for it because size > rarity to almost everyone, thus palms sell for more on average. Best go for the gold if selling. Your shard is probably a bit different. GL.
