Numista and Krause list this coin for 2003, but is it also known for 2002, or is the 2002 a mule??

Also, note that Krause lists this coin (KM 240) as silver gilt; and lists another commemorative for the event , with a different design, as silver plated bronze (KM 105). My coin appears to be silver plated, rather than silver.
