There were two "series" produced around the same time: for Livonia and for Riga. Riga is, of course, part of Livonia, but because of the whole "free city" part their coins were issued separately.
The Livonian series have something like "Solidus Livoniae" in legend, and a different shield. Your coin is definitely for Riga, and so is the coin in that Krause picture (no, I don't have an idea why either).
As for Numista, they seem to work under the "Riga is part of Livonia" version (note that the entry is even actually labeled "Free City of Riga").
Unrelatedly: I don't know why did Krause do it, but IMHO calling these coins "silver" is wishful thinking. They're billon, and pretty low-end billon at that (I couldn't find a definite figure - and yes, I searched for it just yesterday, for reasons unrelated to this thread - but one study about XRF detectors claimed the silver content was 10% by 1652).
