This depends on the condition. If it is circulated, likely face value ($1). If uncirculated anywhere from 3 to 10 dollars or so
30-40 dollars more than the face value
Mint condition uncirculated...$6,000.00
That depends largely on its condition, if the serial number has a star in it, and which bank it was issued from. I can help: send a scan to support@papermoneysite.us

Face value. Star notes are used to replace individual notes on a sheet that are spoiled in printing, and are fairly common.
$100.00, UNLESS YOUR A COLLECTOR IT THEN MAY BE WORTH MORE TO THAT PERSON.
The selling price for a five dollar star note is 12.00 to 14.00 dollar.
$10 in uncirculated condition. $2 if used.
The collector value for a $1 star note is usually only about two to three dollars.
If circulated, only face value or slightly more. Uncirculated, perhaps $3 or $4.
