Stack's sale of October 22, 1943 offered a complete set of trade dollars through 1883 and was one of the finest quality groupings to be auctioned up to this point in time. The owner was obviously a connoisseur. Even so, while the Philadelphia Mint coins are all represented by Proofs, not all of the branch mint pieces were Uncirculated. There were three notable rarities: Uncirculated examples of 1873-S, 1876-CC, and 1878-CC.
