I am curious if this is common. This bill has an 2 letter prefix and I haven't been able to find any info on it.
There is an *IL prefix listed but nothing with 2 letters without the asterisk.
Does it have any additional value?

That is the two letter prefix that was used when the series was first printed. They will all have the
Lawson-Bouey signature. Later on they switched to a three letter prefix. As there were over
1Billion 800 Million 2 letter prefix dollar bills printed, yours would be only worth $1.00 in that condition.

Thanks coinguy

too many people kept these 1 dollar banknotes when they were replaced by coins. it isn't rare and worth almost face value unless in near perfect condition or a rare or a special prefix/serial number
