Looks a little fakey-wakey to me. But for a buck? http://www.ebay.com/itm/161351000572?ssPageName=STRK:MEWAX:VRI&_trksid=p3984.m1423.l2661
Yep, if it were only $3 then I'd have to bid on it. I mean the seller has a feedback rating of 2, so you have to know the guy is legit. Especially since he is in Russia.
10 roubles 1887 for $ 1?! It is the madness! It is a golden coin; rather expensive even in Russia. It looks like a copy.
The seller says in description "copy of a gold coin". So no need to guess. Google Translate can be very helpful if you don't know Russian (or any other language).
