This is a pretty poor fake currently for sale on eBay, probably not surprising it is from Bulgaria
from the listing--
"this is a very rare coin to bid only people who know what is a very rare coin
the price is US $ 4.500.00 if not reached will not send
please do not mock coin of the rare
guarantee 100% authentic
not send in Bulgaria
photos are not good Live is much more beautiful"
The real examples of this coin have what has to be one of the best obverses of LRB's
