“prison money”
A remarkable example of prison camp currency from the Jáchymovské Doly (Jáchymov Mines) labor camp in Czechoslovakia, issued in 1945. The note features an elegant geometric pattern in gold and cream tones with a central shield design and corner numerals in circular frames, rendered in uncirculated condition with no visible wear or damage. This unlisted Pick number represents a poignant piece of World War II history—emergency currency used within a notorious labor camp system.
Scarce. Prison camp currency from the Jáchymovské Doly facility is rarely encountered in numismatic commerce, and this Pick-unlisted 5 koruna denomination from 1945 represents a specialized collecting category with very limited documented survival. The camp's history and the temporary nature of the currency system mean surviving examples are infrequently offered for sale. However, without definitive mintage data and given the specialized nature of this collecting area, a conservative assessment of 'scarce' rather than 'rare' is warranted.
This 5 koruna note was issued by the Jáchymovské Doly labor camp near Horní Slavkov in Bohemia during the final year of World War II. The camp operated as a uranium and other mineral extraction facility under Nazi control, later becoming notorious as a Soviet uranium mine during the Cold War. The inscription 'Národní Podnik' (National Enterprise) reflects the official framing of the operation, while the geometric shield design represents institutional authority rather than national symbolism—typical of camp scrip that existed outside normal currency systems.
The obverse features a purely decorative Art Deco-inspired geometric pattern comprising repeating interlocking diamond and shield-like shapes arranged in a regular grid across a gold and cream background. A large central shield or institutional crest in a lighter shade serves as the focal point, with text inscriptions integrated around and within this heraldic element. The reverse is blank, presenting a uniform cream-beige surface characteristic of emergency prison currency that prioritized rapid production over elaborate design. The color scheme and geometric motifs suggest deliberate differentiation from standard Czechoslovak currency to establish the note's auxiliary status within the camp economy.
Front side: 'JÁCHYMOVSKÉ DOLY' (Jáchymov Mines), 'NÁRODNÍ PODNIK' (National Enterprise), 'HORNÍ SLAVKOV' (Horní Slavkov, the town name). Back side: No inscriptions present. The note is denominated in koruna as indicated by the large numeral '5' shown in circular frames at top corners.
This note appears to have been produced using letterpress or relief printing, evidenced by the clear, uniform geometric patterns and solid color fields. The regular repetition of the interlocking shield pattern and the crisp definition of the corner numerals are consistent with metal type or engraved block printing. The production method was likely intentionally simple and rapid, suitable for emergency wartime camp currency that did not require the sophistication of national banknote printing.
This note is cataloged as Pick-unlisted, indicating it does not appear in the standard Pick catalog of world banknotes. No serial numbers, signatures, or date variations are visible on the observed example. The geometric pattern design appears consistent across the observed note, with no evidence of different printing runs or overprints. Further documentation of known varieties would require access to institutional archives of the Jáchymovské Doly facility or specialized collections focused on Nazi occupation currency.
