I suppose in order to make it easier to tell the different denominations of bills apart quickly. With different faces one can easily distinguish a ten from a twenty, etc. Even people who can't read can learn that the different faces have different values.

Please check your bills again and post a new, separate question. No US $1 bills were dated 1987.
Assuming that you are referring to portraits on currently produced US bills (and not, for example, all of the people depicted as signatories of the Declaration of Independence on the back of the $2 bill), the answer is 2 - Alexander Hamilton appears on the $10 bill and Benjamin Franklin appears on the $100 bill.When considering all US bills, the $10,000 bill produced from 1928 to 1946 has the portrait of Salmon P. Chase. Chase was Treasury Secretary under Abraham Lincoln and instituted the U.S. Treasury's first legal paper notes during the Civil War.

No. US one dollar bills were not made in 1950.
US T-Bills use a/360
US bills weigh 1 gram. There are approximately 453.59 g in a US pound. So either the answer is $453.
Yes, many millions of them. All US $2 bills were printed as red-seal US Notes from 1928 to 1963. Most $2 bills issued before that also had red seals but weren't necessarily US Notes.
The US Congress passed a law that ordered the US mint to issue these coins. The plan was to get people to use the one-dollar coins in place of the paper dollar bills and save millions in replacement costs. ( I do not know which Congressmen or senators pushed for the law.)
On current bills:Hamilton - $10Franklin - $100On bills no longer in use:$10,000 - Salmon P. ChaseAlexander Hamilton and Ben Franklin of course.Salmon P. Chase was on the $10,000 bill when there were larger denomination bills printed. A bit of history shows he did just about everything in American Politics. He was U.S. Senator, a Governor, Secretary of the Treasury and Chief Justice of the Supreme Court.
