Here is another set I have, its comes in a card presentation card. Is the is this original with the coins?
There are two gold coins in this set. Again after google I found they are liechtenstein gold ducat coin, year 1728.
The google photos show clean edges to the coins mine look rough edged and not perfectly round almost like they have been stamped and not finished. Sorry for my lack of technical terms! Anyway pictures say a thousand words.....
