1989 Round Table 20 Złotych

This 1989 Round Table 20 Złotych coin features a design that includes the iconic round table itself, symbolizing the negotiations that dismantled communist rule in Poland.

Struck at the Warsaw Mint, it was produced in silver with a diameter of 38.61 millimeters, marking a shift from the propaganda-heavy coins of the People's Republic. The obverse still carried the Polish eagle, a holdover from earlier issues, while the reverse depicted the table and participants, a bold nod to the talks that began in February 1989.

Mintage figures are unclear; records from that era can be spotty. As for the joke, some might say the coin's value rose faster than Poland's GDP in the 1990s—briefly.

That said, it's a straightforward piece from a pivotal year.
