Sig Sauer p229 RTT

Hello all, I am as green as they come to handguns and a buddy of mine told me this was a smokin deal. So, I went for it. Turns out I am reading online that the reverse two tone is really rare. My questions are
1)How rare is it? (that might keep me from shooting it like I lived in the wild west), and
2)How much do you think it's worth? (To tell if it really was a good deal or not.)
Thanks for your time.
