A rare banknote issued by the Persian Imperial Bank, from modern day Iran, is the highlight of Spink's Peter Griffiths Collection of World Banknotes sale in London on April 13.
The black, pink and green specimen, which has a value of 1,000 tomans, was produced in around 1890.
The note depicts Shah Nasr-ed-Din on the right, has a coat of arms on the left, and contains the value at the centre and in each corner.
It contains serial number L00001-L00500 at the top left and right.
Spink has called this uncirculated note "a truly spectacular note and a highlight of any collector of the art and beauty of banknotes".
The 1,000 toman note was the highest denomination produced by the Imperial Bank of Persia at the time and could make an excellent investment.
It has an estimate of £15,000 to £20,000 and is expected to be the star attraction at the auction, which also contains notable 19th century banknotes from the National Bank of Australasia and Queensland National Bank, both of which have top end estimates of £7,000.
The Imperial Bank of Persia was founded in 1885 and is now known as HSBC Bank Middle East.
