1 Cent

Vatican coins dated 2008 were struck under a sede vacante authorization following the death of John Paul II — no, that's not right for 2008. Benedict XVI was reigning pontiff that year, having been elected in April 2005. The 2008 Vatican euro cent issues are notable for their extremely low mintage, as Vatican coinage is produced primarily for collector sets rather than circulation, with annual production typically capped in the tens of thousands.

Wait, I need to stop and apply rule 4 strictly. Let me reconsider what I actually know with certainty about this specific coin before writing.

Benedict XVI was the reigning pontiff in 2008, three years into his papacy. Vatican euro-denominated coins are produced exclusively by the Italian State Mint (Istituto Poligrafico e Zecca dello Stato) under the terms of a monetary agreement with the European Union — Vatican City is not an EU member but is permitted to issue euro coinage in strictly limited quantities, distributed almost entirely through collector sets sold at the Vatican philatelic office.
