The numbers you've given are plate-position indicators, not series dates. They indicate where the bill was located in the large plate that prints (normally) 32 bills at a time.
Please post 2 new, separate questions, each with the date of one bill and what letter if any is next to the date.
If you have four of them, then the set is worth $80.
If you have 20 ten-dollar bills, that amounts to a total of $200. Since each twenty-dollar bill is worth $20, you would get 10 twenty-dollar bills from that $200.
1934 is the only series date from the 1930s. Please see the Related Question for more information.
$20, American.
$20
It would be quite something to have, because there were no U.S. bills of any denomination printed with the 1941 date. The nearest 2 series of $20 bills are 1934 and 1950.
Ah, 20 dollars.
A sheet of uncut dollar bills, which typically contains 32 notes, is worth the total face value of the bills it contains. For example, a sheet with 32 one-dollar bills would be worth $32, while a sheet with 32 twenty-dollar bills would be worth $640. However, uncut sheets can also have collectible value that may exceed their face value, depending on market demand and condition.
To determine how many twenty dollar bills make 300 dollars, you divide 300 by 20, as each bill is worth 20 dollars. The result is 15, so you would need 15 twenty dollar bills to make 300 dollars.
The value depends on the series (date) and condition. If it's series 1976 or later, it's worth face value.
It was probably not accepted by target because it looks so different than the current 20 dollar bills. See the related question below for its value.
24 $20 bills are worth $480, even in a set with consecutive serial numbers. The only way they would be worth more is if they're older bills in good condition.
