I've had these 4 coins for a while and I have no idea what they are and what they're value is. Someone help me please. Thank you. Im posting a pic of each obverse and reverse.
First two coins look like mine below. Christina, Queen of Sweden (1632 - 1654 A.D.) BI Solidus O: CHRISTINA D G R S, Monogram of Christina under crown, Vasa royal crown within monogram. R: SOLIDVS · CIVI : RIG, Crossed keys in ornamented shield surrounded by legend. Minted in Riga 1633-1654 16mm .64g KM 21
The last one is Hungarian denar of the king Matthias I (1458-1490). Like mine coin. My guess: your coin was released between 1482 and 1486.
