I usually pride myself on being a fairly diligent researcher but after 2 days and 6+ hours of deep-crawling the Web in German and English and looking at lots of auction catalogues I must admit defeat and ask for the Community's help with these two coins!
These are uniface or "einseitiger" (one-sided) Pfennige from probably the late 15th-early 16th c. if I had to guess based on general design. Tiny little silver coins, 12mm or less.
My best guess so far is that these are Swiss and possibly Chur Bishopric issues based on the general design. I don't think they are German but I could be wrong there as well, maybe Bamberg but that is a stretch. The lion (?) doesn't have the Bohemian "two rings" tail I would be able to identify easily. (I'm assuming it's not a gryphon or an ibex.)
The first coin has a shield (arms) divided quarterly with what appears to be two lions (?) rampant in the upper left and lower right quarters respectively and a field of dots in the lower left quarter; encircled by a beaded border. It has a tiny hole in the middle.
The second coin has a beaded border with a single lion (?) rampant. The border has a diamond instead of a bead across from the lion's left rear paw.
If someone recognizes either of these two motifs and can help me nail down an issuer that would be great!
Have a good evening & stay safe!
