Without seeing the bill it's difficult to estimate a value, but depending on a number of factors its value could be anywhere from $100 to several hundred. Those factors include whether the serial numbers are completely missing or printed on the back side of the bill, how old the bill is, its condition, and so on. You should have the bill examined in person by an expert in currency errors.

As you have seen in many other postings, a bill's serial number almost never has anything to do with its value.
Worth about 4 to 10 dollar depending on condition
The "8894" serial number is a red flag. Regardless of denomination, nearly all Bank of the United States bills with that date and serial number are modern reproductions that have no value to collectors.
The serial number alone isn't enough to assign value, but rather the series year and the condition. Without more information, it's assumed to be worth one dollar.
Depends on year and how low the serial number is.
The percentage of a partial bill really has little to do with its value. Any bill is worth its face value if it contains a complete serial number and any part of the other serial number.

Without knowing the series (date) and condition, the best possible answer for now is two dollars.
Face value.
The value is more dependent on the year (series) of the bill. The serial number by itself isn't enough information.
Impossible to answer without a serial number and detailed description.
