What's the value of a five dollar bill with serial number 05050505 .2009

$5 sounds about right. There's nothing special about this bill. It's only 6 years old and there's nothing special about the serial number. There is likely a similar bill for each Federal Reserve Bank that year - and every year before and after that year. If it is in mint / un-circulated condition, tuck it away and *maybe* your great-great-great grandchild might see it gain some value.
