I paid 40e for my q10 earth froggy 3 months ago, and saw multiple offers in that range around the same time. Unless something has changed drastically I would expect 50-60e.
EStorage wands are really, really unpopular. Being Q9 makes it a collector's item, but you likely won't find much demand for it. Unsure on an exact price but I'd expect that one to fluctuate a whole lot.
