This year is very common eventhough in F, scarcer in XF-UNC condition. The 2 kopeks 1867 EM/SPB, 1868 SPB, 1869 SPB, 1870SPB, 1871 EM/SPB, 1876EM and 1892 SPB are much scarcer, some are almost impossible to find.
I have lots of russian coins for sale at bargain prices on my Delcampe.net store :
Mostly copper coins of 19th century. Take a look.
Thank you !
