Anything pre-1947 has 50% silver content and therefore contains its value in silver. A few of those George VI shillings (1947 - 1951) look in high grade and would be worth a pound or two, though not rare. However, at that size, it's unclear whether they have lustre, or have been polished. If the latter, then worth virtually nothing I'm afraid. ok, thanks. They havnt been polished, not by me anyway.
