Hello,
I think these are copper szelag from the Polish-Lithuanian Commonwealth under John II Casimir Vasa’s reign but there seem to be quite a few types and I don’t know which mine belong to (partly also because they are pretty worn). Can anyone identify these?
The 1665 coin:
o. IOAN. - CAS. REX.; under bust is T.L.B.
r. SOLI. MAG. DVC. LIT. 1665 ; under horse and rider is the monogram HKPL
Gumowski. Handbuch der Polnischen Numismatik, p154 #1870.
The 1666 coin:
Same legends. There are four varieties; two have the HKPL shown on your coin.
#1871 has TLB under the bust.
#1874 has TZH under the bust.
Your coin appears to be #1871.
