I have a chance to buy this coin for a really low price. The only info i have is that it is a poland 3 polker from early 1600"s. not sure if that is correct, but any info would be appreciated.
Surprisingly it is a cheap coin. KM#41 3 Poltorak dated 1624 with a "24" in the Orb Sigismund III Good=$1 VG =$3 Fine = $6 VF = $10
Your coin was released in 1624. It was very numerous type of Polish coins. They are not expensive in Russia too ( about $4 for each coin). I have small set of such coins too.
