Lamar Miller auto

I’ve been wanting to get a Lamar Miller auto for some time now and a couple weeks ago I found the one I wanted. I got an auto of his from 2012 Topps Inception 13/25. It’s currently worth $60 and I paid $30 which I think is fair. As a guy that played at the U and is now playing for the dolphins and should be their starting RB this year, I have high hopes for him and think he can be one of the top backs in the NFL which will hopefully increase his card value.
