Hello,
I have a question about the Russian 3 Ruble banknote (Pick #9c) with Shipov signature, dated 1905.
My banknote has the prefix: ѲН (Fita-N / Ѳ-Н)
I'm trying to determine which issuing authority it belongs to:
Russian Empire (prefixes ФЕ-ЧХ)
Provisional Government 1917 (prefixes ЧХ-ѲѲ, АА-АН)
R.S.F.S.R. (prefixes АО-ГѲ)
The problem:
According to the historical Cyrillic alphabet (Wikipedia and other sources), the letter Ѳ (fita) comes after Ф, in this order: ... Ф - Ѳ - Х - Ц - Ч - Ш - Щ ...
However, according to Colnect catalog, the prefix range "ЧХ-ѲѲ" suggests the order: Ч - Ш - Щ - Ъ - Ы - Ь - Э - Ю - Я - Ѳ (as if Ѳ comes at the end)
This creates a contradiction:
If Ѳ comes after Ф (standard alphabet), then ѲН should belong to category 1 (Russian Empire)
If Ѳ comes at the end (as Colnect suggests), then ѲН belongs to category 2 (Provisional Government)
My questions:
What was the actual order of the Cyrillic alphabet used for banknote serial prefixes before 1918?
Which category does the prefix ѲН belong to?
Did banknote series follow the standard alphabet order, or was there a special logic?
Thank you for any help!
