“8-dig ser #”
This is a VF-grade example of the Estonian 1 Kroon on 100 Marka (Pick-61b) from 1928, featuring a striking red overprint conversion from the earlier mark-denominated note. The note displays exceptional preservation with crisp, vibrant colors—orange, green, red, and cream—and no visible circulation wear, creases, or foxing. The ornate classical architecture vignette in the central oval, combined with elaborate grape vine and floral corner motifs, exemplifies the artistic quality of interwar Estonian currency design.
Common. The 1928 1 Kroon on 100 Marka conversion is a standard regular-issue note from Estonia's currency reform period with substantial print runs. eBay market data shows examples in Fine condition selling for $34-$62 in 2018, with catalogue valuations for VF grade at $150 (2016 data). These price points indicate healthy collector demand but no scarcity premium. The note's designation as Pick-61b represents one of two documented variants, but both variants remain common in the market. The 8-digit serial number format and absence of rare serial number characteristics further confirm standard commercial production parameters.
This note represents a critical moment in Estonian monetary history, issued during the transition from the post-WWI mark currency to the new kroon standard established in 1928. The overprinted text 'UKS KROON' (One Kroon) directly over the original '100 MARKA' (One Hundred Marks) denomination reflects Estonia's currency reform following independence and stabilization of its economy. The Treasury of Estonia's issuing authority, prominently displayed as 'EESTI VABARIIGI KASSANTI,' underscores the young republic's assertion of monetary sovereignty.
This banknote features a classical architectural building depicted in a central oval vignette on the front, likely representing an Estonian government or financial institution building from the period. The design is framed by elaborate decorative elements including grape vine motifs with fruit clusters and ornamental scrollwork in all four corners. The back side emphasizes the denomination through large, ornate numerals '100' positioned within scalloped decorative frames on both left and right sides, with an ornamental cartouche in the center containing the legal tender declaration. The overall aesthetic reflects the high-quality engraving standards of interwar European currency production, with intricate background pattern work and fine line details throughout. The red overprint conversion represents the practical solution employed by Estonia to transition existing mark-denominated currency stocks to the new kroon system without complete reissue.
FRONT SIDE: Serial number (upper left): 1092449818 | 'EESTI VABARIIGI KASSANTI' = Estonian Republic Treasury | 'UKS KROON' = One Kroon (red overprint, center) | '100' = Denomination numerals (left and right sides) | 'SADA MARKA' = One Hundred Marks (original denomination) | Serial number (lower right): 4924981S. BACK SIDE: 'UKS KROON' = One Kroon (burgundy text, top center) | '100' = Denomination numerals (left and right sides in scalloped frames) | 'RIIGIKASSA-TAHT ON VA-BARIIGI PIIRI-DES SEADUS-LIK MAKSU ABINÕU' = State Treasury note is a lawful means of payment within the borders of the Republic | 'SADA MARKA' = One Hundred Marks (original denomination, bottom center).
This note was produced using intaglio (engraved) printing, as evidenced by the fine line patterns, intricate background details, and crisp definition visible in both the decorative elements and text. The deep engraved line work in the grape vine motifs, ornamental scrollwork, and security pattern details are characteristic of high-security banknote production of the 1920s. The red overprint text 'UKS KROON' was applied as a secondary printing operation, likely via lithography or flexographic printing, after the original mark-denomination notes were produced. Estonian banknotes of this era were typically produced by established European security printers, though specific printer attribution for this issue requires additional documentation.
This note is catalogued as Pick-61b, representing the 1 Kroon on 100 Marka conversion overprint variant. Pick records two variants for this base number (P-61a and P-61b), indicating minor differences in overprint or printing characteristics between issues. The observed serial number format (1092449818 / 4924981S) follows standard Estonian Treasury patterns. No exceptional serial number characteristics (such as low numbers, repeating digits, or special prefixes) are evident in this example. The consistent red overprint quality and placement suggest mid-range production from the conversion program rather than an early or late printing variant.
