Economy - overview:

This unique, noncommercial economy is supported financially by an annual contribution (known as Peter's Pence) from Roman Catholic dioceses throughout the world; by the sale of postage stamps, coins, medals, and tourist mementos; by fees for admission to museums; and by the sale of publications. Investments and real estate income also account for a sizable portion of revenue. The incomes and living standards of lay workers are comparable to those of counterparts who work in the city of Rome.
