An uncirculated (no wear or folds at all) bill with his signature can go on ebay to a collector for up to $5.
Unless it's uncirculated, face value only. Even though Barr served as Treasury Secretary for only a month or so at the end of the Johnson administration, bills with his signature continued to be printed for a long time afterwards so they are not particularly rare. As of 05/2012 U.S. Currency Auctions lists a fair market value of an uncirculated Barr note at only $2.00. Many sellers on eBay are under the mistaken impression that these bills are rare - or are trying to play off others' lack of knowledge - and are attempting to charge highly inflated prices.

Joseph Barr was Secretary of the Treasury for a few months in late 1968 to early 1969, and his signature only appeared on $1 Federal Reserve Notes. These all bore the familiar green seals and other printing used on current $1 bills. In fact, the last red $1 US Notes were printed about 40 years earlier. Please see the Related Question for more information.
Please check your bill again and post a new, separate question. Barr's signature only appeared on series 1963 B $1 bills. Even though Barr served as Treasury Secretary for only a month or so at the end of the Johnson administration, $1 bills with his signature continued to be printed for a long time afterwards.

Many sellers on eBay are under the mistaken impression that these bills are scarce - or are trying to play off others' lack of knowledge - and are attempting to charge highly inflated prices.
So-called "Barr notes" (1963 B series $1 bills) are worth no more than other $1 bills of the same time period, about $1.25 in circulated condition and $2 to $4 if uncirculated.Barr notes have an undeserved reputation for rarity. Because Joseph Barr served as Secretary of the Treasury for less than a month at the end of the Johnson Administration, many people assume they were only printed during that month. In fact, the Treasury frequently prints bills from a particular series long after the officials shown (the Secretary of the Treasury or US Treasurer) have left office. The 1963 B series continued to be printed during most of 1969, with a total run of nearly half a billionnotes. Many who speculated by hoarding Barr notes were left with piles of paper each worth only a dollar each.
