Except for World War 2 most medals are named on rim so they are very easy to identify. There are hundreds of different regiments and of course different ranks for medals from 1799 to the present day. Lots of very good replicas of British Military Medals and replacement medals are sold to museums. Replica Medals are exact copies of the original British Military Medal for a certain campaign and supplied with ribbon and a plastic envelope to protect the medal. These are cast medals in high quality alloy if they come from a good dealer.
The replacement medals are die-struck so they are more expensive. Struck in nickel gilt and polished in silver gilt they cost more because these have made by a master craftsman who has carved out by hand and small machine – a “die”. This “die” can cost around two thousand dollars alone. Then you have the actual striking which is completed by a machine usually with a 250 ton press capacity.
Collectors, dealers, ex forces associations and even whole families frame replicas for show. This way, members of the same family can display their ancestors medals. It is usual for owners to keep the original medals in a safe or bank. Part of the reason is British Military Medals can command a very high premium indeed.
