Pinecone round bowl verification?

Bowl measures about 5" high. Handles on either side; one is a single branch and the other a double or split branch. If I move the bowl under direct light I can barely make out the word Roseville on the bottom and can't make out if anything else is below it. The writing is very difficult to see. More photos available if necessary but the mark won't photograph. My parents had the bowl for many years and it was left to me. They didn't know anything more than it was something they loved.
Appreciate your opinions. Thank you
