1960 2 Złote Poland

The 1960 2 Złote coin was one of the first Polish issues to use an aluminum alloy, making it remarkably lightweight for its denomination and helping stretch scarce resources in a postwar economy. That choice reflected the practicalities of mass production under central planning. The obverse shows the Polish eagle within a wreath, a design element carried over from earlier socialist coins, while the reverse features the denomination and date in a straightforward sans-serif font.

Records indicate it was struck at the Warsaw Mint, though exact mintage figures for 1960 are murky—likely in the millions, given its role as everyday currency, but precise numbers vanished with old archives. The coin's edge is plain, a common trait for these pieces, which saw heavy circulation without much wear due to their soft metal.

I suppose if you drop one, it might just bounce away unnoticed, much like certain economic policies of the time.
