If we assume that the mass of paper is the same in a bill of each denomination, and
the mass of ink in each is also the same, then the value of any mass of $10-bills is
10 times the value of the same mass of $1-bills.
So the difference in their value is nine times the number of bills in either pile.
There were no 1901 dollar bills

Reading the question very carefully, I'd have to say "none". If the stack consists of "900 dollar bills",then there are no "50 dollar bills" in it.But the questioner is probably referring to equivalent values.900 dollar bills have a face value of $900.00 . In order to match that same face value with $50.00 bills,you need 18 of them.
10 ten dollar bills
If there are d $1 bills their value is $1 × d, or d dollars.Each $5 bills is worth 5 times as much so if there are f bills their value is $5 × f, or 5f dollars.Thus the expression for the total would be d + 5f dollars.

There weren't dollar bills in 1775 and the first dollar bills didn't happen until 1862.
No one answer, as there is more than one series of bills, and multiple different defects. The greater the number and nature of the defects, the higher the value- but it WILL need a hands on appraisal.
