It would depend on the date and condition of the note. A modern issue $10 star note in circulated condition is worth about $11, maybe a little more if you find the right seller. An uncirculated note would be $15 or so, if the serial number is special (like all 1s, 2s etc or 12345... etc) it may command a higher price. There is no such thing as an absolute value for any coin or bank note (unless it's made of silver/gold/platinum) their values are derived from how much they currently sale on average. You may find someone who would only pay $10 for it and others who might pay $200, it all depends on the buyer.
