$60 if worn, up to double that if in nearly-new condition.
On the 5 dollar bill: Redeemable in gold on demand at the united states treasury or in gold or lawful money at any federal reserve bank. 1928 series A A.W. Mellon secretary of the treasury
The phrase "redeemable in gold" indicates your bill was printed before 1933, but a specific date and series letter are needed. Please post a new question with its date and what letter if any is next to the date.
There should be a gold seal, not a green seal. Green indicates a Federal Reserve Note. If you have a Gold Certificate with that date, its value in circulated condition is $250.-$750. depending on how worn it is. If you have a Federal Reserve Note, it's more common and is in the $125.-$180. range.
Even though your bills have the phrase "redeemable in gold" on them they're Federal Reserve Notes rather than gold notes. $10 gold certificates were also printed in the 1928 series but they don't have any series letters. 1928 A $10 FRNs are definitely worth more than 1928 B bills, but the difference depends on the issuing Federal Reserve Bank letter. Please see the questions "What is the value of a 1928 A US 10 dollar bill?" and " ... 1928 B ... " for more information.
Q - Can you see Federal Reserve bond 1934 series US 500000000. NO. Actually you could, but if you saw one it was fake, as there is no such thing as a "Federal Reserve Bond".
The Federal Reserve, for example, collects data on monetary policy and financial institutions and publishes that data in the Federal Reserve Bulletin.
More information is needed, like series date, condition, and is it a Federal Reserve Note, Silver Certificate, Demand Note, or what?
No, only for the Federal Reserve Bank of Minneapolis
The phrase is actually "Redeemable in Gold" rather than "Backed by Gold". Federal Reserve notes were and remain so-called fiat money, i.e. paper currency that represents an obligation of the central banking system that is not dependent on precious metal. The phrase was removed from Federal Reserve notes starting with the 1934 series, issued the year after Franklin Roosevelt took the US off the gold standard. It had appeared on previous Federal Reserve notes beginning with the first series in 1914. Strictly interpreted, the full phrase limited gold redemption only to those bills presented at the Treasury itself or any of the twelve Federal Reserve banks, places that the average person would rarely visit. The clause "... or lawful money" was never clarified but was interpreted to mean any coin or bill issued by the government, including other Federal Reserve notes.
There is no series 2006A.
Face value for all of them.
