1867 Proof Nickel Pattern - J-584b
Strike TypeCoin Details
Description
A second compositional variant of the J-584 design, this "b" suffix variety represents yet another planchet type tested with the same die pairing. The existence of multiple suffix varieties for a single die combination underscores the Mint's emphasis on metallurgical optimization alongside design refinement. The copper-nickel alloy presented production challenges beyond die wear, including planchet preparation difficulties and striking pressure requirements that differed from the Mint's extensive experience with softer metals. Cataloged as PCGS #61825.
