What are the two characteristics that dollars must have to be accepted as money in our society?

I think its the spider and the line along the side I'm not sure

but i think that the line along the side is one of them.I had that question before but i can't remember what were the exact answers.

Is this a question about a) the physical characteristics of a dollar as Kalin-jasm-sis suggests, or b) is this a question for a basic micro/macro economics course?

If a) then I don't know. If b), a dollar bill must (1) have the expectation that the dollar will be accepted as a form of payment anywhere else in the U.S., and (2) have the expectation that the dollar will retain all or most of its purchasing power in the near future.

The two characteristics that dollars must have to be accepted as money in our society are:

1. Acceptability: Dollars must be widely accepted as a form of payment by individuals and businesses in our society. This means that people should be willing to receive dollars in exchange for goods and services without hesitation.

2. Stability: Dollars should maintain a relatively stable value over time, meaning they should retain their purchasing power. If the value of a dollar were to fluctuate significantly or unpredictably, people would lose confidence in using it as a medium of exchange.

To determine if this is a question about the physical characteristics of a dollar bill or a question for a basic micro/macro economics course, it would require further clarification from the person asking the question.
