Known Charm Sets

Pokedoll charm sets were released in small waves. To date, 27 individual charm sets have been released. For sets released from 2002 to 2005, each set has a date listed on the back of the item or on one of the Pokemon if no item was included. For sets from 2013-2015, no year is printed on the charms. Instead, ©Pokemon is printed on the back of each charm in the set.
