Mite box
The term mite box (also alms box or poor box) refers to a box that is used to save coins for charitable purposes. Contemporary mite boxes are usually made of cardboard and given out to church congregations during the Lenten season. The mite boxes are collected by the church, and the donations are given to the poor. Mite boxes are popular with children because they can fill them with small change, teaching them the principle of giving to the poor. The Mite box giving promotes the spirit of contributing based on the intent to help others and not on the monetary amount.
