I have a few MGP finishers medals I look after, two of them are early ones. The first is dated 1947 and is silver hallmarked. The second has for some reason had the date partly etched out, but looks like 1939 also hallmarked silver. The presentation box they are in has a Jewlers name of C Wallace 29 Victoria Street Douglas. If you look closely at them, there are small changes in the design between the two. The later ones I look after are not dated apart from one, 1999 and they are not silver hallmarked, and you can see at least two more designs. Some of the the presentation cas is not marked, some others have Toye Kenning & Spencer LTD who where the people who made at ACU TT badges.
