Voc - 1 Duit - 1798 Possible Fantasy Or Counterfeit?

Briefly I wondered if the engraver might have flipped the dates on a 1789, but I can't find a 1789 either ... As you say, the word DUIT spelled out this way seems to only occur for 1792: https://www.acsearch.info/search.html?id=2238547

That leaves the only other chance as a 1792 with some kind of defect at the base of the 2 making it look like an 8. Any chance there is/was a countermark on the obverse at the location of the 8 reverse?

Thank you both for your input. You have given me some new leads to persue.

The link given by tdziemia gives a better image of a 1792 example. It is not impossible that there is a 2 under my 8, but I consider it unlikely without further evidence.

I also got a catalogue reference from that link: Scho. 1316b. This is from the book "De Munten van de Nederlandsche Gebiedsdeelen Overzee 1601-1948" by C. Scholten (title translated "The Coins of the Dutch Overseas Territories"). This book is old (first published 1951) but at least gives me something to look for.

Searching online for that book led me to a Dutch Coin forum: https://www.munthunter.nl which has a substantial number of threads on VOC coins. I'm not sure if my Dutch is up to posting there, but I guess I'll have to try.

Reading there I did find out that the Ceylon VOC coins were counterfeited for the tourist trade (tourists to Sri Lanka), so perhaps this is what I have.

Although I still don't know what I have, I am further along, so thanks again.
