The National Bank of Moldova issued new silver collector coin "Carol (Kolyada)" on December 9th 2011. Coin has been issued under Holydays, culture, traditions of Moldova coin series.

Kolyada or koleda (Cyrillic: коляда, коледа, колада, коледе) is an ancient Slavic winter ritual celebrating the Old New Year. It was later incorporated into Christmas. The word is still used in modern Belarusian (Каляды, Kalady, Kalyady), Bulgarian, Macedonian, Serbian (Коледа, Коледе) and Croatian, Czech and Slovak (Koleda). Some suppose the word was borrowed the word from the Latin calendae; compare "Kalends". Others believe it derived from Kolo, "wheel". Another speculation is that it derived from the Bulgarian/Macedonian word "коля/колам" (kolia/kolam), which means "to rip, to kill (a man), to cut animal for eating", or from the Serbo-Croatian "коло, колодар" (kolo, kolodar). Some claim it was named after Kolyada, the Slavic god of winter or Koliada, the goddess who brings up a new sun every day.

Coin renders the image of a group of carol singers and it is issued to promote the traditions about the winter holidays, dating from ancient times.
