Are coronation issue ducats considered to be commemorative ducats (and therefore coins) or are they considered to be medals/jetons? Do they reside in a grey area, technically being commemorative ducats but also medals/jetons as they were not intended to circulate? Take for example the 1867 Franz Joseph coronation ducats. They produced these in gold, silver, and bronze. For the gold they used the ducat planchets and for the other medals they matched the ducat planchet size. The silver and bronze are always considered jetons, however, the gold issue is frequently referred to as a ducat. See the below EPN example which is listed as ducat on the slab but is also graded as a medal: Then they issued a 1 3/4 ducat size for this coronation as well. This was not uncommon and you can go back several hundred years and see the same two ducat and 1 3/4 ducat sizes for the coronations. This one from the EPN collection had no denomination listed - they simply put "Gold" instead of 1 3/4 ducat. Again, graded as a medal. Interestingly the 1896 millennium jubilee ducat was purely a commemorative and not intended to circulate but is also exclusively referred to as a ducat. I tried to find a picture of a slabbed one, but NGC is incorrectly slabbing them as goldgulden so it's not really illustrative of my point. I've been collecting this 1867 coronation series (36 types) for a number of years. I have most of the silver issues and have discovered an unknown mule, but I've only recently acquired my first gold coronation type in this series. As I'm also writing a catalog of coins for this period, it dawned on me that I should include the gold issues if they are ducats, but perhaps not if they are medals. Thoughts?
