For sale - all of the'Y' Series Litho Printed machin stamps from all sources. All printers - Cartor / Questa / De La Rue / Walsall Y1760 through to Y1790.These stamps appeared in various booklets - usually but not always containing machin stamps at the appropriate. Some also appeared in'counter' booklets, most appeared in Prestige Books. They were pre-security gummed stamps, issued between 1993 and March 2011. Some of these stamps are only sourced from one book, and that book may have contained one copy of the stamp. So some of them have a high catalogue value now. The descriptive strip under each stamp gives the source, date issued and printer. The strips will be included with the stamps, which will be sent on pages as setout in the photos. Where possible a small piece of the surrounding paper from the Presige Book page is still left attached. Obviously counter book stamps have no surrounding paper. The photos show a typical set - I have several of them, so the surrounding / attached paper will be slightly different for each set. But all of the stamps shown will be included.
