Silver Spoon

I have 4 silver spoons and I’d like to learn more about them if anyone can help.
They are a very simple design and after some research I believe they are made by James Dixon and Sons, based on the name Dixon and the trumpet. The other two markings are the letters MR and NS.

I’d appreciate and information on
When they were made?
Are the silver or just silver plated?
Are they worth anything?

Any info would be much appreciated.

Sorry but i can’t upload a pic because it says
“Sorry, but the maximum filesize for all Attachments is reached. Please contact the Board Administrator if you have questions.”
I’ve made the file tiny but it still won’t work.
I’ll try later.
