E.P. Zinc flatware made in Italy silver plated

I know absolutely nothing about silver. I do know I received this as a wedding gift 8 years ago. The person who gave it to me is unreachable. I know it is dirty because i have not looked at or cleaned these since I got them. I do believe I lost some pieces when I moved. but again I am unsure. On the back is E.P. Zinc made in italy. I think this was a 12 person setting. The pieces are 10 forks, 12 spoons, 12 knifes, 11 tiny spoons?, 2 large serving spoons. No reserve and bidding starts at a crazy low 99 cents. Shipping will include insurance.
