Hi Folks, Have been reading the forum for some time (thank you!) but joined today to post. My father had a fairly small collection of coins but never got round to sorting it very well before he passed away, I'm currently trying to sort it and am enjoying the experience and feeling close to him. Initially I was very excited when I came across what I thought to be a Gold Sovereign, however I have now read up about fakes but am still too much of a novice to be able to tell the difference. It is Edward VII 1904, I assume made in London (Please see attached pictures) I don't have very accurate scales but it weighs between 4-5grams - I think a bit light? Any advice on its authenticity (and how to tell!) would be much appreciated!
