Everyone can buy in museum "denary chorzowskie" (I have problem with english name, because polish 'denar' is a word used for Roman silver denarius, gold dinard, french denier, etc. the coin is in fact made of brass). Denomination of the coin is '4 denars', that is exactly 4 zloty's (0.89 euro; 1.20$; 0.78 GBP; 115.15 JPY).
On the face of the coin (above) is the town coat of arms. On the reverse (below) is the Post Office.
