Five Shillings 1951, Help Please

These coins were issued in 1951 to commemorate the Festival of Britain, a large exhibition and festival held on the South Bank of the River Thames in London.

They are made of cupro-nickel and 1,983,540 were struck. They are usually referred to as 'Proofs' but they were not struck to the same standard as modern Royal Mint proof coins. Some catalogs now refer to them as 'Proof-like', which is more accurate.

As they were minted in large numbers and are not made of silver, they aren't particularly valuable. My latest catalog lists them at £8 in Uncirculated. Ones in the original cardboard boxes of issue might fetch a little more.

Thank you very much, what a wonderful guys.
