Ron Guth:
The 1884 Half Dollar is a wonderful, low-mintage date. In fact, circulation strikes are scarce enough that collectors often resort to purchasing Proof examples of the year just to fill the hole in their collection. Because of the low mintage, many 1884 Half Dollars are fully Prooflike and, in fact, are sometimes confused as Proofs. Conversely, Proofs are often so frosty in appearance that they are confused as circulation strikes.
The overall quality of this date is excellent. Most examples grade out at MS64, but there are also tidy populations in MS63 and MS65. MS66 examples are no more rare than MS65s, but in MS67, the 1884 Half Dollar becomes truly rare.
