Is this an error coin.

Found this in a Tot lot the rim is higher on one side also wider 1991 P. I also didn't think Philadelphia put mint marks. I am a total novice when it comes to anything about coins thank you for your knowledge in advance if it is an error, can you give a rough value.If you saw this coin in todays finds sorry didn't realize this forum existed.

not really an "error" . . . more just poor minting by the mint! I guess it is kind of a minor error. Maybe the collar die is a little worn out and making that effect. Or, it could be a minor mis-aligned die making that side of the rim larger. What-ever it is it wouldn't bring much $ over it's face value.
