For my money it is a fake made from dies that have been made from a genuine coin or an old die that has been reused. It is not a modern copy and it would be a very rare die that was not blundered after being finished with. The close ups of the edge just doesnt look right for a circulated coin that has been cleaned in a bad way. The only exception would be a coin cleaned by heating in a vacuum with an oxygen getter and there arent many people who can do this (or at least risk it with a coin going to be sold) I did a few test pieces about 5 years ago but on Roman stuff from a hoard that were all the same mintage so different cleaning methods were tested on them as none were rare. The problem is the oxygen getter may sputter on to the coin and give strange readings. The cleaned coins often have a shiny blackened finish, not unlike pewter.
