The Vatican sells an interesting assortment of coins and coin sets honoring Popes, Papal topics, and other subjects of interest to Catholics. The online Vatican coin store is easy to find (there is an English version available) but they do not take orders over the Internet.
In order to buy these coins, you will need to call, fax, or email the Vatican's numismatic office to see what is currently available for sale. The Vatican does have a listing of a few of their Euro coin sets online in English (along with the prices in Euros) but to access the full inventory, it is best to email them (and yes, someone there will reply in English.) Some of the coin sets shown on the Vatican Web site have been sold out for years.

This is the direct link to the Vatican Coins and Stamps Store entry page. Click on the link that says "Numismatics" to see the few coin sets listed. If you hunt around a little, you can find some miscellaneous coins and medals listed, but most of them have been long sold out.
You can contact the Vatican's coin sales office at firstname.lastname@example.org, or call them at 011-39-06-6988-3708. Keep in mind that their normal business hours will be about five hours ahead of those in the U.S. Eastern time zone.
The Vatican State government also maintains a Web site, which has a coin-selling store on its site, but the store has never actually opened for business. It lists many coins, medals, and sets that are different from the ones on the Vatican Web site.
In order to buy coins directly from the Vatican coin store, you will first need to become a client. The first step is to contact the Vatican in order to request an application. After the application is filed with the Vatican, it may take up to five years for them to approve the application. This process is to mainly cater to large volume coin dealers and not individual coin collectors. In other words, they are looking for large clients that will buy wholesale lots of Vatican coins.
If you are eager to buy Vatican coins, you will need to find a third-party coin dealer that deals in Vatican coins.
Variety of Coins
The Vatican has been making coins for hundreds of years. Currently, they use the Euro standard currency. However, they also produce many commemorative coins and medals celebrating different people and events throughout the year.
