When I limit the issuer in the search bar to "Breslau, Bishophric of" or "Breslau, Prussian bishophric of", the page doesn't load (or is mislinked?). Happened with Chrome and Firefox.
The same happens when you click on the respective links of the coins countries (for example here and here). Makes sense, because they should end on the same page. I don't know if other countries have the same problem. I could only find these two.
