Russia 1839 Borodin Ruble. (counterfeit) An exceesive rare ruble coin, the number of such coins left are said to be around 20,000 but there are also untold number of such coins made into jewelery etc. Note that this example of counterfeit can be told easily by the mass and the hair of Alexander I. This coin mass is only 20.5g opposed to 20.73g. What is funny is that this *supposely* coin is proof-like, which makes it much more ridicious. :) Let this coin image be a good illustration :)
