Ron Guth:
The 1905 is a scarce, low-mintage date, but it is readily available in Mint State, particularly at the MS64 level. MS63 and MS65 examples are of approximately the same rarity, though the latter is considerably more expensive than the former. As tough as this date might be, it is one of only a few in the series that is represented by an MS68 example -- in this case, a PCGS MS68+ -- making it the single best Barber Half Dollar of any date certified by PCGS. Not surprisingly, that piece was once owned by Dr. Steven Duckor, whose eye for quality was unsurpassed. When it coin sold in 2010, it brought $132,250, a record price for ANY Barber Half Dollar.
