Very rare destruct, caused by striking with a damaged stamp, which began to disintegrate after cracking. The chipped stamp fragment can be seen on the coin in the form of excess metal, above the coin's relief. The amount of metal "sucked in" on the reverse caused it to be missing on the reverse, hence instead of the inscription "Rzeczpospolita Polska", it is "Rzeczpos a Polska". This type of destruction, arises extremely rarely, because the technical control at the mint, already at an earlier stage of destruction of the stamp should replace it with a new one, and coins struck with a damaged stamp should be sent to remelting, instead of circulation. RARE.
