Zookeeperz I think you are right, there is something wrong with this coin. I don't know if milled coins were double struck ? or if old coins that had been in circulation of the correct weight were collected and re stamped in the mint ? looking at my coin under the legend there is the same design but different shaped letters and as Zookeeperz said the lion at the top of the coin has another lion underneath and slightly to the right.
Plus looking to the left part of the reverse the shield with the two leopards, they look double struck but the leopards underneath look different, a much finer design but perfect compared to the ones stamped above.
