Serving Forks?

Hi,

I’ve always assumed that these were serving forks to serve large dishes, but they have been in my father’s belongings (who passed away years ago) and I’ve always been curious to find out exactly what they are, how old they are, and if they are of any value.

They both have “STERLING” stamped into the shaft on the backside. They’re about 10-11" long and 3.3.5" wide. Any insight would be greatly appreciated!
