1 Ducat - Josef Johann Adam

Josef Johann Adam ruled Liechtenstein from 1721 until his death in 1732, but this ducat type was struck — and restruck — across an extraordinary span ending in 1968. The Liechtenstein mints produced official restrikes for collector demand well into the twentieth century, a practice common among small European principalities whose original issues were too scarce to meet numismatic interest. The restrike program was entirely sanctioned and cataloged, which is why Friedberg lists the type without distinguishing dates.

The ducat specification itself — .986 fine gold at 3.49 g — follows the centuries-old Habsburg ducat standard that Liechtenstein observed as a matter of economic necessity given its position within the Austrian sphere.
