The count is something around 2200 variations last I heard but there are people working on other details like the attire of the horseman (hat, beard, pigtails etc.) so that number will grow as students look at more coins. The coin here is a rather
rare one and many times nicer than most of the
mint and time. With a little looking you can get a set of one from each
mint that produced them (15 official and you might want a barbarous one for
good measure). Going for a full set seems a
bit overkill but a well organized group of about a hundred coins would do well to represent the series.
Traditionally we separate the coins into four groups according to the pose of the horseman but there is a variation of the 'seated' ones that I believe should be given separate listing. The image below is from my
