nothing, its a counterfeit.
Please post a new question with the bill's date. Without that important piece of information it's not possible to value the bill. Also, the motto wasn't added to $20 bills until the 1960s so if your bill is older than that, the missing motto is perfectly normal.
The phrase "In God We Trust" was first included on U.S. coins in 1864 during the Civil War era. It became the official national motto of the US in 1956 and appears on all US currency, including the dollar bill.
There is no such thing as a 1957 atheist 50 dollar bill. The value of a 1957 $50 bill would depend on its condition, rarity, and demand among collectors. It would typically be worth its face value unless it is part of a rare series or in pristine condition.
The symbols MOCCXXVI on a dollar bill likely represent the roman numerals for 1126. However, they do not hold any special significance or value on a dollar bill.
They are not really "Godless". NO American banknote (paper money) carried the words "In God We Trust." until 1957. The motto was permanently placed on all bills beginning that year as a political reaction to the threat of Soviet Communism which was an officially atheist system. The 1935 series of bills was actually printed into the 1960s so some of the later issues do carry the motto, though most do not. You'll need to know what letter if any is next to the date to determine its collector value.
What is a 1950 one hundred dollar bill without "In God We Trust" worth?
It is worth $5.00
$1
If a dollar bill were printed in 1977, it would be worth $1.00 right now (in 2008). If a $20 bill were printed in 1977, it would be worth $20.00 right now (in 2008). A candy bar that may have cost $0.05 in 1977 would cost around $0.75 now. But then, a candy bar isn't a dollar.
At the time, it was worth one dollar.
a half hundred dollar bill is worth $50
It's worth 5 dollars.
I suspect a $100 dollar bill was worth exactly $100 in 1935!
A 100 dollar bill is worth 100 one dollar bills.
what is a 1934 thousand dollar bill worth
A 1986 Canadian 5 dollar bill is worth $10.00
Dollar bills are not always worth one dollar, however one dollar bills are worth one dollar for the sake that 1=1, it is a one dollar bill, and can be exchanged for goods and services.
