Ad from my UK newspaper today : not worth a zloty [13]
Polish bank notes:
Polish coins:
- all bank notes and coins MUST have an eagle with a crown - old PRL ones had an eagle without a crown
- no coins in current circulation are made of pure aluminium or silver or have a nominal higher than 5 zł (coins with higher nominals are only struck in silver or gold for collectors/investors and nobody sane would use them to pay in everyday transactions, since the intrinsic value of precious metal they're made of is much higher).
I read of someone tricking a shop assistant into accepting this 30 lat prl silver coin here - its nominal is 200 _old_ złotych, its (numismatic) value is about 35 new zł.
