Prelates often give away their skullcaps to the faithful. The practice, which was started in the modern era by Pope Pius XII, involves giving the zucchetto to the faithful, as a keepsake, if presented with a new one as a gift. Popes John Paul II, Benedict XVI, and Francis have continued the custom. The pope might choose not to give the visitor his own zucchetto, but rather place the gift zucchetto on his head for a moment as a blessing, then return it. Bishops, cardinals and archbishops such as Fulton J. Sheen frequently gave their old zucchetto in exchange for the newly offered one; Sheen also gave his zucchetto as a keepsake to laity who requested it.
