hi its andy here, i lost my login info and couldn't retrieve it, just had a reply from them, and this is what they say Dear Thank you for your enquiry. The object in question appears from the images supplied to be a commercially produced British medal commemorating the coronation of King Edward VII and Queen Alexandra in June 1902. The registered design number on the medal is consistent with this date. The medal seems to be that recorded in Laurence Brown's British historical medals 1760-1960, vol. 3, no. 3849, but no manufacturer is given. Many such medals were manufactured for sale to the public.
