With the release of the collector's book "History and Printing Technology" on September 1, 2008, Liechtenstein Post set new standards in modern stamp marketing. Published to commemorate the 400th anniversary of the Princely House of Liechtenstein, the work, thanks to an unexpected feature, became one of the most spectacular new releases in modern philately.
The book documented the creation of the commemorative block featuring the portrait of Karl I of Liechtenstein and, in addition to the regular perforated edition, contained numerous printing stages (phase prints). It was only shortly before publication that it became known that an imperforate block was also included. This exclusive addition instantly made the collector's book a highly sought-after item. With a retail price of just 69 Swiss francs and a strictly limited edition of only 5.000 copies, the entire edition sold out within a short time.
Demand in the collectors' market rose rapidly. After the imperforate block was considered Michel After Block 18B received its own catalog entry, its catalog value developed exceptionally quickly within just a few years. The initial valuation of 80 euros was raised to 250 euros in 2009 and to 400 euros in 2010. It was still listed at 2026. MICHELThe catalog lists the block at 550 euros and first-day covers at 750 euros. At the same time, the catalog warns of forgeries where perforated stamps have been subsequently trimmed.
The widespread attention is primarily due to the small print run: while the regular anniversary block was printed around 195.000 times, only 5.000 copies of the imperforate block exist. This rarity, along with the unusual distribution method, led to a veritable price rally immediately after its release. At times, first-day covers fetched more than 500 Swiss francs, and specialist dealers also saw exceptional potential for appreciation in the issue.
The market has since calmed down considerably, as recent auctions and dealer listings for 2026 demonstrate. Initial speculation has given way to more realistic pricing. However, genuine postal receipts and used franking stamps with the imperforate block remain particularly sought after, as their rarity continues to command high prices.
Almost two decades after its release, the imperforate edition of the 2008 anniversary block is still considered a significant modern rarity in Liechtenstein philately. It impressively demonstrates how limited editions, skillful marketing, and high collector demand can create a philatelic highlight – but also that valuations, expectations, and actual market prices can diverge considerably in the long run.
