Hello! Is your coin made of real gold?! If it is so and not a copy/fake of base metal,then it is ''tilla'' of the 3-rd. reign of Muhammad Khudayar Khan in 1865-1875 (AH1288 = 1871,for your coin).
As a gold coin it has a catalogue (K.M.) value of 300-400usd. in medium or better quality (even 500$ for an XF specimen).

P.S.: I repeat,if gold & original! If fake,then it is worthless…
