The idiom "a dime a dozen" has its origins in the United States and is believed to have emerged in the early 20th century.

It is a way to dismiss or deride a subject or situation as insignificant.

The idiom "hill of beans" originates from the United States and was popularized in the mid-20th century. It is used to describe something as insignificant, unimportant, or of minimal value, much like a pile of beans would be considered a small and relatively worthless quantity.

The idiom "small potatoes" originated in the United States during the 19th century and was associated with the idea of small, insignificant, or unimportant things.

The idiom "chopped liver" has Jewish origins and is commonly used in American English. It originates from a traditional Jewish dish called "gribenes," which consists of crispy bits of chicken or goose skin and onions that are often considered a delicacy. However, "gribenes" is not as highly regarded as chopped liver in Jewish cuisine, and thus the expression "What am I, chopped liver?" developed. This idiom is used to express feelings of being overlooked, unimportant, or undervalued, comparing oneself to something less significant.
