This picture I made may help. On a proof the inside of the rim goes straight down to the field or surface of the coin. On circulation coins, there is a curved slope away from the rim to the field of the coin. The top of the rim will also generally be very flat and generally squared off on a proof where the circulation strike may be a more rounded rim.
