Hi, thanks for all of your swift and helpful replies. Looking at the Coin Yearbook 2013 it gives the price guide\Mintage for the coin I posted as:
Mintage 20013
F £500, VF £1100 and EF £4000
As "Benny who" stated in his post one sold at Baldwins for £840 (Condition Cleaned, scuffed with surface marks and hairlines, otherwise good fine and very rare) in the link below:

I think I will hang fire on the melting down route until I do some more investigating.
Once again thanks for your assistance it was much appreciated.
