1814/3 50C Overton 101a MS63+ 认证号35594632, PCGS号39488

The first die variety of 1814 Half Dollars is presumed to be Overton-101a since it is a left-over 1813 die converted to 1814. As a result, traces of a 3 can be seen beneath the 4 on most specimens, though it may be difficult to discern on low-grade examples. 

This die suffered mightily during its life.  Early states show clashmarks from where the two dies hit each other without a planchet between them.  Either the clashing, weakness in the die, or both resulted in die cracks at the base of the date, through some or many of the stars, and from the reverse edge to the left wingtip -- these got progressively worse as the die continued in priduction -- until it simply gave out or was retired from service.

1814 O-101a is the advanced state of the dies and this appears to be the most common version.  Paisley called it Rarity 2 (Common) in the Tenth Edition of Overton -- this applies only to circulated examples, as Mint State 1814 O-101a's are quite rare.  The best example appears to be the PCGS MS65 from the Link Collection.
