Info on forks and spoons in the United States

I picked up four each of these spoons and forks today at an antique store. The forks are salad forks and the spoons are teaspoons. The forks are from WA Rogers and Sons, labeled "AA" and the spoons are by Community Silver, aka "Oneida." There are no other markings on the spoons. I believe them all to be silver plated, and from the 1910s, but I'm not sure exactly when. Any info , especially how much they are worth, would be greatly appreciated!
