Description
The plain-edge copper companion to J-827, this pattern continues the systematic approach of producing each die combination in multiple metals and edge treatments. The regular Seated Liberty obverse and Standard Silver wreath reverse appear here in copper with a smooth edge, completing the copper pair in Group 1 of the dime series. J-828 exemplifies the methodical precision of William Barber's 1870 pattern program, where each design combination was explored across a matrix of compositional and edge variables to provide comprehensive data for any future coinage reform.
