A yellow fluorescent coating was added to all German stamps starting in 1962 with the Mainz issue. Before that, selected issues from the mid 1950's to 1962 can be found both with and without this coating. Scott calls this fluorescent paper, but it is really a form of tagging, because the paper does not natually exist in this state. The comparison picture shows several stamps from the 1961-1964 definitive issue with and without this tagging to show you the difference.
