We've recently moved my 75 year old mum into a new flat, and unpacking, discovered a 1900 half sovereign, which appears to be a London mint (there's no obvious mint mark).
However, what I have noticed under the magnifying glass, is a pair of very small marks to the right of the date, that I've not seen on any other half sov photos.
Is this just a glitch in the minting process or does it actually mean anything?
