Description

Transitioning from the systematic design groups into the die trial territory that closes the 1870 half dollar pattern series, J-991 represents a transitional striking using die combinations from the Standard Silver program. Struck in aluminum with a reeded edge, this piece falls outside the neat six-variety matrices that organize the preceding groups, indicating it was produced to test a particular die pairing or to satisfy a specific collector request. Die trials and transitional pieces from the 1870 series are especially prized for the insight they provide into the Mint's internal production processes.

Rarity Notes

R-8. Very rare, estimated 3 or fewer examples known.
