Article 1 Section 8 of the US Constitution states that "The Congress shall have Power To:..." (among other things) "To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures;" Clearly it is the Federal government that has the right to coin money.

These were powers specifically given to the Federal government by the Constitution. States cannot produce money- only the Federal government. States also do not define what is a pound, what is a mile, etc. Otherwise, a bushel of wheat in Virginia might be a different size than a bushel of wheat from Maryland.

Yes, unless you are refering to other constitutions, for example back in the 1700's the states created there own constitutions. Fun fact is that the draft for the US constitution was basically the New York Constitution written by John Jay. Other countries also have constitutions; so if you only say, "the Constitution," someone from India might think that you are talking about the Constitution of India. By saying the US Constitution, it is more definite which constitution you mean. However, if you say, "the Constitution", while you are in the US, most people would assume that you are talking about the US Constitution.

They are always written, because by writing down a Constitution you 'fix' its provisions. After that, a Constitution always is very hard to change or make Amendments to. And that makes it rigid.
Many Federalists advocated for the creation of a new government because they thought that the Articles of Confederation did not give the makeshift federal government enough power to maintain a cohesive nation. For instance under the Articles, the federal government could not levy taxes or regulate any sort of relations between the states. Every state had the right to print its own money which created a huge number of problems with inflation and banking. To fix these problems, Federalists wanted a new, more powerful federal government, hence their Federalist moniker.
The United States Constitution attempted to ensure the preservation of individual liberties, rights and powers belonging to the individual States and to the people of those states, by enumerating and limiting the powers that the Federal government could have over the States and over individual Americans. While the Constitution's framers tried to establish a Federal government strong enough to prevent the colonies from possibly separating from the Union into separate countries, they also attempted to limit the powers of a Federal government that, they feared, might someday become as tyrannical as that of England had been over the former American colonies. The United States Constitution also provides for administrative matters related to the Federal government, such as the order of succession to the Presidency if a sitting President dies or cannot otherwise perform his duties.
