10 Kopiiok 1 Kopiika planchet, Pattern

During Ukraine's early post-independence period, the National Bank experimented with planchet specifications before settling on production runs. This piece — a 10 Kopiiok die applied to a 1 Kopiika planchet — is a documented pattern rather than a mint error, produced deliberately to test dimensional tolerances and striking pressure across mismatched blank stock.

The 2002–2014 date range reflects ongoing refinement of the kopiiok series, a coinage that had itself only stabilized after the hryvnia's reintroduction in 1996 following years of karbovanets-era monetary chaos.
