[Price Check] Mare color horse?

[Argleb_310]

I dont think its considered a rare but i dont see them running around anymore, but was wondering what they are valued at, i have one and keep getting mistaken as a tamer, so i wanna sell it. but want to know the value first. its got same stats as a horse but has pure mare color

For the pure black one there like 15-25m the others are 10-15m (depending on shard)
