Within the family of 5 lira notes dated 28 March 1334 (1918), issued by the Ministry of Finance of the Ottoman Empire under Sultan Mehmed Vahdeddin, collectors usually distinguish several sub-types by the Emission stamp on the back. Among these, Pick 109b (with a 6th Emission stamp) is the relatively common type, while 109a, 109c and especially 109d are all very rare – with 109d regarded as the rarest of the group. In the main Turkish catalogues of Ottoman paper money – first in the works of Mehmet S. Tezcakın & Güçlü Kayral and later in the updated catalogue by Kayral–Büyüktuncay–Uslu – this rare subtype appears as number 198 E-5 / VA-2 T3: 5 Lira, 28.03.1918, 5th Emission stamp, signatures Cavid (front) and Cahid (back), Series H only. The online catalogue OttoCollect.com, today the most up-to-date digital reference for Ottoman notes, records this same subtype as Extended Pick 109d. For years, only one example of 109d was known and illustrated there – a circulation note with serial number H054350 – and in print it was effectively treated as “unique”. Recently, however, a second note of exactly the same type has come to light. It is again a 5 lira of 28 March 1918 with a clear 5ᵉ EMISSION stamp, the same Cavid/Cahid signatures and the same Series H, but carrying a different serial number: H053905. This confirms that there are now at least two recorded examples of the 5th Emission, Series H: • H054350 – the classic catalogue example; • H053905 – a newly recorded note, scheduled to appear in public auction on 7 December 2025. Following the documentation of H053905, the entry for Extended Pick 109d on Ottocollect.com has already been updated: the rarity status is no longer “Unique”, but RRRRR – still an extremely rare note, yet no longer a lone survivor. For specialists in Ottoman paper money, this is a small but important adjustment to the rarity map of the 1918 5 lira series. It also illustrates how modern tools like Ottocollect, combined with careful recording of serial numbers by collectors, can quietly rewrite what we thought we knew about the scarcest issues of the late Ottoman Empire.
