I got it from the Cash Shop during the half off sale and I'm trying to decide if I should use it or sell it... how much do they go for these days?

If you hold onto it, you can probably sell for 60mil or so. But since the sale just ended, people probably won't want to pay that much yet.

I sold one not too long ago for around 63mil. I agree with Jovi, just tuck it away for a while and wait c:

I had bought one for 50mil a month or so ago.

Thanks for this post, was wondering the same thing. :)
