Identify and or Value of Sterling knives

I have 5 of these small knives which measure approximately 6 1/2 inches long. They are marked sterling on both sides of the handle. There are no hallmarks.
Any information and/or value would be of interest to me.
Thanks!

The style and marking is consistent with American, early 1900s. Assuming the blades are silver plated steel and the sterling handles are hollow, I’d venture they are worth about $15-20 each.
