I have two of the twelve frozen deaf lions in the game. How much would one be worth?

I have this girl on my side account (this account) that I won in a raffle that I entered with 200 sb —> https://www.lioden.com/lion.php?id=794121550388

Then I have this little boy I traded a gmo cow and three crunchy worms for on my main account —>

While I love them both, I’m not sure I want two deaf lions and I’m considering selling one; although I’m not sure what they’d go for.
