The O-123 1795 Half Dollar is the second or third rarest die variety of the year (a lot depends on whether the O-118 actually exists).  Estimates of the surviving population range from nine to twelve examples.  In his Spring 2015 listing, Steve Herrman shows 11 appearance of O-123 and O-123a, though there are some duplcations there. 

O-123 is rare because of the early failure of the reverse die which quickly cracked through the final S of STATES through OF, eventually leading to a chunk of the die falling off, rendering it useless (Heritage 1/2008:1339 shos this massive failure).

Most examples of the 1795 O-123 variety are low grade or impaired.  There is one standout, however -- an NGC MS65 that last appeared on the market in 2005.
