Like the previous type, Classic Head Large Cents were struck from pure copper, with a weight of 10.89 grams (168 grains) and diameter of approximately 29 millimeters. All pieces have a plain edge.
Production quality varies greatly, as did the quality of the planchets. The large cents of 1814 are notoriously known for being struck on planchets of inferior quality, due to the impact of the War of 1812. Additionally, many coins of this type were weakly struck, giving even uncirculated examples at first glance the appearance of a circulated coin.
Cherrypicking for the best examples is advised, and it might take a considerable amount of time to find problem-free examples with a good strike on an above average planchet.
