Technological sample of the last type of PRL dime.
Interesting, since at least 5 main page stamps were used for the issue of these samples (that's how many for the brass prints Janusz Parchimowicz managed to separate).
Variety with a large PRÓBA inscription, far from the denomination numeral.
Mintage of 10 pieces (according to NBP).
Brass, diameter 22 mm, weight 4.13 g.
