The value of a 1973 US 1 cent coin is 1 cent, or $0.01. However, some 1973 1 cent coins may have additional value due to their condition, rarity, or mint errors. For example, a 1973 1 cent coin that is in uncirculated condition (i.e., it has never been used in circulation) may be worth more than a 1 cent coin that is in circulated condition. Additionally, some 1973 1 cent coins may have mint errors, such as die cracks or off-center strikes, which can increase their value to coin collectors.
