A dime a dozen意思

"A dime a dozen" is an English idiom that means something is very common and not particularly valuable because it is available in large quantities. The phrase suggests that an item or a type of person is so abundant that it could be bought or found for just a dime, which is a very small amount of money.

For example, you might say:

"In this city, pizza places are a dime a dozen."

This means that there are so many pizza restaurants in the city that they are not considered special or rare. They are easily accessible and not particularly expensive or valuable.

The phrase is often used in a casual, conversational context and can be used to express a lack of interest or excitement about something because it is so common.
