You have a remarkable coin in your collection: an 1889 Indian Cent, minted in Philadelphia with the Mint Mark "P". This coin is categorized as a one-cent piece, also known as a penny, and is composed of bronze. The Indian Cent series is celebrated for its iconic design, featuring Lady Liberty adorned with a feathered headdress on the obverse and a laurel wreath on the reverse. This particular piece is not just any Indian penny; it is a Proof coin, which indicates that it was specially struck to provide a high-quality finish, often used for collector sets rather than general circulation. With a mintage of only 3,336 coins, this limited production makes it a more coveted item among numismatists. The dimensions of the coin measure 19 mm in diameter, with a weight of 3.11 grams, typical of Indian Cents from that era. Due to its unique properties—specifically its year, mint mark, limited mintage, and proof production status—this 1889 Indian Cent carries significant value and collector interest in the market, particularly among those who appreciate the history and craftsmanship of early American coinage.
