1 Grosz Trial Strike 21/V under O in Grosz

Polish coinage was being reorganized following the reestablishment of the zloty in 1924, and the mint at Warsaw was actively testing die combinations and letter punches throughout 1925. This piece — a trial strike carrying a positional variant with "21/V" punched beneath the O in "Grosz" — reflects the systematic die-proofing process used to document punch placement before committing to production runs. Such documented trial variants were retained as mint records rather than released, which explains their extreme rarity outside institutional collections.
