Определение монеты

Добрый день.

Я вижу что эта монета 
Empire of Sikh (Indian states)

N#73821

Подскажите какой точно год моей монеты?

There is probably no intentional variation of the dies based on the year of issue and there was probably never any documentation connecting specific dies to specific years. Except for Chinese cash coins this is the standard situation for all base metal hammered coins which are listed as “ND” in reference books and in Numista.

понятно, спасибо
