This is a set of three Villeroy and Boch Castell Switch 3 pattern dinner plates.  They each measure 10-5/8" diameter and are in very good condition with no chips or cracks and very minor scratching that can only be seen if tilted in the light.  They are white porcelain with a checkerboard border and were available 1996-2020.  They are listed on a china replacements site on the web for $59.99 each.  Any questions, please email.  Thanks!
