Vintage Royal Crown Derby Cup and Saucer Mikado Pattern Dover Shape

Royal Crown Derby Pattern Mikado Cup and saucer Cup is Dover Shape I believe the II on the bottom of the mark, dates the saucer to 1939. On the saucer, the dot with a circle around under the Royal Crown Derby stamp I think indicates it is dated to 1925. I am no expert but believe this is very old china. 1930s Blue Mikado Teacup and Saucer. A tiny delicate China teacup. Dover Style Appropriate measurements Cup Height 2.3” Diameter 2.9” Saucer Diameter 5.5” Condition Both saucer and mug have seen little use. The gold trim and pattern are in great condition. There are some tiny spots and blue smudges on the cup and underside saucer. I think part of the manufacture? Cup No chips, cracks or crazing Saucer I found a tiny chip on the under rim. (A flea bite?) The price reflects this flaw but this chip is only noticeable when you run your finger on the underside of the saucer. See pictures and ask any questions
