The only one among the nickel samples for the 20th anniversary of the Polish People's Republic directly referring with the front side to this (XX YEARS OF THE PRL on the material on the ears), and not just with the dates on the eagle side, as in previous ones.
A very nice design by Waclaw Kowalik, loosely referring also to the first two-zloty coins of the Second Republic period.
Mint condition.
Nickel, diameter 33 mm, weight 14.77 g.
