Hello all I need help!
I have had a wonderfully rare Dark Brown Heavy Rosette (Slot 8) born!
There are 26 of them in game, including mine, and no kings with this mark.

I am looking to sell her, but I am within a conundrum and don't know how much she's worth!

I'm originally thinking around 10-15GB since she's rare, but I know mottleds are going for only about 1-2GB right now. So looking for opinions please! Picture of her as an adult below!
