All 5-year-plan definitives,issued from 1953 till 1955 were reprinted in 1957. The reprints were printed at 20 millions sets each. They were exported and sold mainly abroad. All,except few "slipped through" stamps bear printed date-cancellations of the year 1956. The cancel were placed central on blocs of four,so that single stamps show a quarter of the cancel. All reprints were printed on ungummed paper.So gummed stamps cannot be reprints. The paper of the reprints is smoother than that of the originals. (best seen on the backside) Of the first set (Scott no.155-171),printed by Litho(graphy) the designs of originals and reprints differ in many details. Wether these are minor,as Scott claims,is a question of opinion. As I am myself a "novice" DDR-collector and my collection,that I had bought recently,did not contain the reprints,I found out,that they are not so easy to find. They are not attractive for stamp-dealers,because of theirs very low cat.-values and because they can so easily be confused with the originals. During my attempt to scan the 1953 series,I found that I miss one of the reprints,but will nevertheless show what I have. Talking about cat.-values,Michel lists the 1953 reprints at € 3.- for the set. I have no actual catalogue,what values the originals in used,but in an older issue,the originals were priced used € 110.-,versus € 3.- for the reprints. As no price for originals in c.t.o. was listed,I think they were not sold as such. original,left stamp,reprint right stamp upper original,lower reprint On all originals the A of DEMOKRATISCHE is placed under between the HE of DEUTSCHE,while it is further to the right under the E on all reprints. There are many differences in the design as well. On this stamp,the reprint 1 Pfennig value,the twig and leaves left to the 5 are much less shaded and appear to be nearly white.
