Looks like it sold for a KaW Whoopee, which was then quicksold for 15 keys. Sellers at 17, so won't be more than that.

Sellers at 15 (young), 19, 20 (young), 27.

So in summary there are sales at: 9 (qs), 10 (?), 12 (mp.tf), 12, 15+, 18 (mp.tf), 20 (pure), ~22, 23. Sellers at 15 (young), 19, 20 (young), 27.

I'm afraid we will have to go with a wide range here. 12-20 makes sense, with pure sales in both ends, leaving out two low and two high sales. Feel free to resuggest at that.
