Both of these are 1510 K-G Hungarian Denars under King Wladislaus II. The first has UNGUNGARIE and the PA from PATRONA and ISLAI from Wladislai on the madonna side and WLAD form WLADISLAI and TRONA from PATRONA on the shield side. The second one has a double punched W and S over L in WLADISLAI.
The first has an extra zero in the date showing 15100 but should be 1510. The second is missing the last digit showing 151,but should be 1510-1516. They both have K-G mint marks under King Wladislaus II.
The first is a 1503 K-H Hungarian Denar under King Wladislaus II. It is the first year that Hungarian Denars were dated. The second is a 1500L Salzburg (Austria) uniface pfennig under Arch Bishop Leonhard von Keutschach. These circulated in Hungary. This is the earliest dated coin I have.
