I am aware that Chronos is keen for a response. I have been holding off, because I am no expert on these, and the topic is subject to widely different opinions. A similar query is being discussed on another forum (UK based) with no clear decision one way or another. (I cannot post a link to that discussion as that is forbidden (I believe) on this forum.)
There have been references to an 1853 gothic florin with a stop after the date in several books going back 100 years or so. More recently these have been called into doubt as no one could produce an example to show the feature, and the variety has almost been written off.
In other cases where a stop on other dates appears after the roman numerals, it is level with the base of the last "i" and clearly round. In Chronos's example the stop is irregular and below the line, suggesting a
Cud or die flaw rather than an intended stop. The other irregularity at the top of the last "i" lends weight to the idea that they are
Cuds.
Having said that, it is possible that coins with similar marks led to the listing of 1853s with a stop after the date in the first place.
The other forum shows a coin with a similar feature at the base of the "i", but not at the top and is clearly a different coin. (Also much more clearly photographed, so easier to assess.)
So, debateable whether this is a definite variety, but some collectors may choose to accept it as it may fill the rare "stop after date" box. Others will simply call it a
Cud and so be uninterested.
I hope that helps!
