The 1853-O Quarter Dollar is far less common than the 1853 Arrows and Rays, but it is not a rare coin in circulated grades. In Mint State, it is quite scarce, with only a small handful of pieces in the MS62 to MS64 grade range (at PCGS). The auction record for this date is the NGC MS66 that sold way back in 2002 for $34,500.
