im no expert in russian coins but the back of that 1 Rouble 1834 to my knowledge seems fake... compared to a pic of the real thing

notice in the real one below the pillar there is no space between the value of the coin and the coins edge..were as in the fake one there seems to be a gap...and its awfully clean
and in the front on the real coin notice the difference in Tzar Alexander's chin and nose... and the inverted "N" above his head in the real coin seems to have a much raised line in the middle than the fake one...
just a few points i got in 1 min... and again not an expert just comparing the pic with the real thing
