The first one isn't
medieval,but the lowest mintage of
King Leopold's reign;a 1666 K-B Hungarian Denar,Huszar 1506 and
Unger 1110.
The second is a 1470 n-hammer under Matthias Corvinus;Huszar 717,
Unger 562m,
Pohl 216-13. It is a variant with a
circle in the
legend instead of the point.
The third one is quite common,but I have room for it;a 1390-1427 Hungarian Denar under Sigismund of Luxebmburg;Huszar 576,
Unger 449a,
Pohl 117-1.
