Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
Are you looking for a value, or additional pieces in your pattern?
My apologies for the delay, I was away with no Internet or phone service over the long weekend.
This is what's known as Rosenthal Romance, Winifred shape. I believe what you have is the salad plate, and either the dessert bowl or soup bowl.
The retail value for the salad plate is $12, the slightly smaller bread and butter plate would be $9. The retail value for the soup bowl would be $15, the slightly smaller dessert bowl would be $14.
Please let me know if I can help further.
