The 1793 Liberty Cap is one of the most desired types among early U.S.Large Cents. The typical example is low-grade, usually with one or more problems (corrosion, surface damage, cleaning, heavy marks, poor strike, etc.), so nice, problem-free examples command a significant premium. PCGS has identified only two example with legitimate claims to the Mint State grade. No Red-Brown or Red examples exist. The finest example has a long pedigree going back to the late 1800s and includes names such as Thomas Cleneay, William H. Woodin, and Louis Eliasberg. It's current grade is PCGS MS64Bn and it is part of the incredible High Desert Collection in the PCGS Set Registry.
David Hall: In mint state condition, the 1793 Liberty Cap is the rarest of the three types of 1793 large cents (Chain cent, Wreath cent, and Liberty Cap cent). The PCGS graded MS64BN is the finest known by far. The coin has super mark-free surfaces and rich brown color.
