In general, a semi proof-like surface is somewhat reflective around the devices and the edge of the coin as well as around the portrait. Coins that have not been cleaned generally show an original patina manifested with various golden, orange colors and a thick "skin". Advanced collectors seek such specimens as opposed to cleaned, shiny examples. This series is highly collectible and are relatively inexpensive for an early gold U.S. coin. The astute collector/investor will seek original, problem-free examples and avoid damaged and inferior coins, regardless of the grade. It is also wise to pursue coins authenticated and graded by a leading third party grading service such as Numismatic Guaranty Corporation (NGC) or Professional Coin Grading Service (PCGS).
