I can see no obvious problem with the enthronement medal of 1907, however without physical examination or high resolution photographs I cannot be 100% certain, I would be a liar if I said I could. I work for a London auction house, A person from a certain former British colony south of Canada and North of Mexico sent me some quite good photographs of an extremely rare Italian Renaissance coin, I could see nothing wrong with it, even when it arrived it didn't say fake; however it sold in the auction for a very high price- three weeks later it returned with a report from a highly respected Italian specialist which confirmed, undoubtedly, it was an exceptional quality turn of the 19th/20th century copy, commissioned by an Italian collector, who, if he was unable to acquire a piece would commission the finest forger available to make him a copy. When I broke the news to the seller I was threatened with life changing litigation, hence I am prepared to give opinions with caveats but nothing definitive without proof.
