Unidentified Medieval Coin #1 - Riga?

That looks like it, yes!
(Sadly there's probably not enough detail left to identify the specific pope...)

I checked Riga (and Bremen, just in case) on Numista and in one or two other places, and looked up crossed keys on Saurma. In retrospect I should have looked up crossed keys on Numista too - it would have brought up Venaissin directly.


In the meantime, I managed to identify one of the other coins. Just as I expected, it's a Polish solidus from the 1620s, apparently Bydgoszcz mint. The last digit of the date is sadly covered up by patina (what's left looks like a 9, but that's apparently not possible).

The rest of the 6 coins include:
- a crowned monogram, probably RC or RG, with some visible legend around, other side covered in so much patina that I'm not sure if I could see anything... the seller recommended me a cleaning method, but I immediately forgot it... and I still can't find a match to the monogram; 15 mm
- something with a crowned H surrounded elsewhere by 3 fleurs-de-lis, some legend faintly visible around, almost nothing visible on the other side; 16x14 mm
- a really nice bronze, on one side griffin to right, surrounded by legend, on the other side a short cross, surrounded by more legend; if Saurma is to be believed, this is a witten from Pomerania, but I wasn't able to find a more specific match; 14 mm
- and what appears to be a Denaro Minuto of Genoa, far too dark, worn and just plain tiny to be identified any further than that; ~13 mm
(I might post some photos if/when the pics that I emailed myself from my smartphone actually arrive...)

Also from the same dealer (only $2 each instead of $3, ironically enough), a very nice AE4 of Helena (PAX PVBLICA, Tesorillo 58, possibly RIC 49) and a worn pul of Jani Beg Khan, Golden Horde (the rosette design, which is so instantly recognizable that I've been wondering what it was for months after seeing such coins in some other bins).

Bob you have the eyes of an artist, I couldn't see any detail until you pointed it out with the match.

Might as well mention what the other coins were - or, at least, what I think they were, since I'm not near them to check at the moment...


I no longer recall the details, but I do recall being disappointed that it was also Polish.
Some searching suggested a Wilno mint solidus of Jan II Casimir.

France, liard, 1580s. This or very similar.

The problem with Saurma is that it only covers coins that are covered in Saurma.
...OK, that came out slightly wrong. The point is that, if a coin is actually from a place (e.g. Netherlands) and/or a time (e.g. the mid-17th century) that Saurma doesn't happen to cover, trying to search for it in Saurma can actively mislead.

In this particular case, what I had was in fact a Genoan quartaro, as was immediately pointed out to me once I actually posted the photos.

Another quartaro, in fact; "Denaro Minuto" is just what Numista happened to call it.
