Wedgwood Wellesley embossed border creamware white dinner plates, mid century vintage

Set of four vintage Wedgwood china dinner plates (10 3/4" in diameter) in the Wellesley pattern, plain creamy white color. These have 1950s dates stamped on the backs, but look much older. None have chips or any particular wear, but all have brown foxing and staining. One plate has a brown streak (just a color, not a crack), see photos.
