A penny affair? A mysterious petition in our country, decisions in another countries

Thanks to the petition to the president, the discussion has been revived whether coins with denominations of 1 grosz and 2 grosz should be withdrawn. As for the author of the petition - the versions are different. As for the examples of countries that have already withdrawn coins with the lowest denominations - this is not always true. As for the cost of production of one-penny coins - it is simply a protected secret, but any have lifted its hem.
