What do the 13 coins in a wedding mean? These are known as wedding arras and they are a touching part of a wedding ceremony. The coins will be blessed by a priest and presented to the bride and groom. During the ceremony the groom offers the coins to his bride as a promise that he will always provide for her. Mostly used by Hispanic couples, the arras are meant to represent prosperity for the newly married couple. The arras are round coins, usually 13 coins, that can be either silver or gold in color. These coins are placed in a treasure chest or box.
