What coin-filled New Year's Eve cake is traditionally cut in Greece?

The coin-filled New Year's Eve cake traditionally cut in Greece is vasilopita.

Vasilopita is a Greek New Year's cake or sweet bread associated with Saint Basil's Day and the beginning of the year. A coin is hidden inside before baking or serving. The person who receives the slice containing the coin is traditionally thought to have good luck for the coming year.

Families commonly cut the cake at midnight on New Year's Eve or on New Year's Day. The first slices may be dedicated symbolically to Christ, the household, or Saint Basil before individual family members receive theirs. Customs differ by region and household.

The name comes from Vasilios, the Greek form of Basil. Vasilopita can be made in different styles, including a cake-like version or a yeasted bread. It is not simply a Greek version of a birthday cake: its hidden object, ceremonial slicing order, and association with the new year are central to the tradition.
