If the title is correct, that is the following, "RUSSIA TOP RARE POLTINA HALF ROUBLE 1706 PETER I aEF XF", Peter I poltinas are NEVER for sale at 70 GBP!!! (unless the seller decided to be awfully nice and sells it that price to the first buyer or he has no clue what he's selling)
Perhaps someone knows what auction it is from?
What is more worrying is how the fonts and design styles appear differently in his own auction listing.
