Hildesheimer Rose B&A90

I have what appears to be either a dessert or tea set of Hildesheimer Rose B&A 90. I have done a little research, and it was made in Germany in the 1960’s by Breuker & Adolphs, Wichl, North Rhinewestphilia. It is all in good condition. What is this set worth now and any ideas where could I sell it at? Thanks.
