I don't understand, do you mean by your title you had this coin graded yourself? Or did you buy it already graded? I know next to nothing about large cents, but it the coloring and eye appeal seem like a 62 to me. However, I don't see any bag marks or problems so it's probably tougher to arrive at a suitable grade. Eye appeal matters in mint state, more so in the upper grades of course, but if all else is equal in the lower half mint grades then perhaps eye appeal brought it done some. That's my guess. By the way, I thought I read you got it for 100 dollars.
