Please can you assist with this as I know nothing about it or its value.
Thanks
This is mass-produced, inexpensive electroplate from Walker & Hall, Sheffield. The “I” suggests a date of 1936. Sorry, but it’s not worth anything, since there is virtually no silver or other precious metal.
ETA: The GR inscription makes me think that it was issued to commemorate the coronation of King George VI. So, maybe worth a pound or two to a collector of royal memorabilia.
