Retail in London is around 120 Pounds for a Silver one, or ,with the 1897 Clasp, around the 250 to 275 Pound mark. I dare say you could bargain down from these high street prices at fairs etc. The 1897,is surprisingly more expensive , due, I think ,to demand ,especially as its a Diamond Jubilee Year, in 2012.
1903 Coronation medals were issued by many countries of the Empire and by many groups and organisations including the Police and the Military.
