Extremely fine, exceedingly rare. Nazarana Rupees and mohurs were struck by Ibrahim Ali Khan in 1880 and 1881 - however it is not yet certain which occasion prompted their issuance. The Nawab did get a son (his third) in 1880 but apart from this, not much of significance is known to have taken place.
