My name is ***** ***** I am here to help with your question, however I only assess one item or matched set per question.
At your convenience, please choose one and send photos.
I can also help you start with a quick and easy guideline on what first to look for to help you indicate what you have.
If the pieces you have are stamped EP, SP, EPNS, Quadruple Plated, Britannia or EPBM - then they are silverplated. The majority of silverplated pieces sell for under $20. Depending on what the intended use is, the age and maker, plated pieces can sell for higher. Pieces marked sterling silver or those with proper British Hallmarks or other international sterling stamps, do carry higher values depending on the item, maker, craftsmanship and age. I will be happy to help further if you can provide images here.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
