This change means that there will be no more "Sede Vacante" series of the regular Vatican euro coins, although the issue of commemorative "Sede Vacante" series (usually gold and silver coins), having legal tender in Vatican City only, remains possible. Circulating €2 commemorative Sede Vacante coins would also be possible, if the Sede Vacante period occurs in a year in which Vatican City has not already released two €2 commemorative coins of another subject. Such a coin was indeed minted for the Sede Vacante of 2013.
