Don't you think those shiny objects look like they were made only yesterday? Well, they probably were...
Just in case some of you aren't sure whether or not these are really fakes, I have taken the trouble to copy the eBay image of the 1899 obverse and put it side-by-side with the scan from the Kazakov catalog, also 1899 (just in case there are minor die varieties for later years ... I think there are, but haven't had time to study this yet).
The lettering of the obverse legend was actually copied very carefully!

But with larger and better images, I am sure that minor differences in the shape and/or size of the letters could be seen. In particular, things become immediately clear even with such small images when one looks at the following details:
1. Ear: ... draw a straight line from the top of the ear down to the earlobe. On the genuine coin, the angle is slanted about 10 degrees or so. On the fake, it is almost straight up and down.
2. Top of hair: ... the hair looks much flatter on the fake coin.
3. Beard: ... the contours of the hair in the beard are similar, but not quite.
4. Forehead: ... is receding on the fake (gives that "Neanderthaler look"), and more vertical on the genuine (looks more intelligent).
So please be sure and report these auctions ASAP if you haven't done so already. BTW the seller has responded and is adamant that these are genuine coins. Funny thing ... in the auction description, he states that he knows nothing about coins, yet further down he does seem to know about the different mintmasters.
