Question

If there is a 1 million dollar curreny,I want know about it.How it will be, etc?

Answer 1

If you are referring to US currency, there has never been a banknote issued greater than $100,000, and that was strictly for transactions between banks. Since 1934, the largest denomination has been $100.
What you are asking for does not exist.
