Unsure why KM #746 is a semi-key date as 1.2 million 2 Ore coins were minted that year compared to 615K the previous year and 865K in 1888. The value shown by NGC in their current World Coin Price Guide is VF-20 $5.-, XF-40 $20.- & MS-60 $75.-. I am not an experienced grader but would suggest your coin is XF-40.
I have 4 of these coins for the years 1874, 1875, 1896 & 1905.
