Please add a picture of the pattern on one plate and of the mark on the back. Let me also know how many pieces are in your set and which pieces you have for example, 12 dinner plates, 12 soup bowls, etc. You can add pictures by using the ADD FILES button on the bottom right of your screen. Add one pic, then send and do that again to send another.
I got your photos, thank you. This is the Firenze pattern by Royal York of Germany from the 1920's. I wanted to see pictures to be sure since you said that the pattern was a little different. This is because in this pattern, each plate in a set of 12 had a slightly different bouquet in the middle. Here are the values for 8 dinner plates, $240.00 and 8 salad plates, $80.00. More pieces would be valued at an average of $10 to $15.00 each.
