OK, I think we can be a bit more definitive

Since these are all about the same size, and smaller than the coin in the other post, they are
silver pfennigs of the Livonian Order, struck between about 1401 and 1483.
#1: 1 pfennig, Reval mint 1471-1483, Haljak 80, as linked earlier. Everything is clear enough to read.
Obv: Arms of the Livonian order within beaded circle. o * REVALIE *
Rev: Cross pattee intersecting inner circle. MONETA o *
#2: 1 pfennig, Reval mint. Probably slightly earlier. The obverse is the same. Reverse, the legend appears to read MONETA + o . which is slightly different. There are coins with this punctuation reverse assigned a date range 1424-1471, but they have slightly different punctuation obverse.
#3. I believe this could be a pfennig of Konrad von Vietinghof, 1401-1413 based on the very thick Maltese cross, and the more circular shape of the cross-in-shield:

Very nice and unusual group of coins!
