Hello, I'm an expert in numismatics, which is the study and collection of coins. When it comes to the value of a 1966 penny, there are several factors to consider.

Firstly, the mintage (the number of coins produced) can affect the value. A higher mintage generally means the coin is more common and less valuable. The 1966 penny had a relatively high mintage, which suggests it's not particularly rare.

Secondly, the condition of the coin is crucial. Coins in better condition, especially those that are uncirculated, will be worth more than those that show signs of wear.

Thirdly, the composition of the penny is also a factor. Before 1962, pennies were made of 95% copper, but in 1962, the composition changed to a copper-plated zinc core. If you have a 1966 penny made of 95% copper, it could be more valuable due to the metal content.

Lastly, there are some special varieties of pennies that can be more valuable. For example, if your 1966 penny has an error or is a proof coin (which are specially made for collectors), it could be worth more.

In general, a typical 1966 penny in circulated condition is usually worth just a penny, or its face value. However, if it's in excellent condition or has some unique features, it could be worth more to a collector.

Value: As a rough estimate of this coins value you can assume this coin in average condition will be valued at somewhere around 1 cent, while one in certified mint state (MS+) condition could bring as much as $12 at auction.read more >>
