It's not now redeemable in gold, so it's value is determined by collector demand.
The worth of a 1928 fifty dollar bill redeemable in gold on demand in very fine to AU condition will vary. You will need to take it to a collector, or someone who can appraise money. Without actually seeing it, it is hard to put a price on it.
If very worn, $250; if nearly new, $750.
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
Could be worth something, depending on its condition and variety (signature combinations, variants, etc). Send a scan, I appraise for free: support@papermoneysite.us and will buy notes too.
All 1928 $100 FRNs carried the wording that they were redeemable in gold. There's more information at the Related Question.
All 1928 $5 Federal Reserve Notes carried the phrase "Redeemable in Gold", although they weren't gold certificates and in fact no gold certificates with that denomination were printed. Please see the question "What is the value of a 1928 A US 5 dollar Federal Reserve Note?" for more information.
$60 if worn, up to double that if in nearly-new condition.
All 1928 $20 Federal Reserve Notes carried the phrase "Redeemable in Gold", although they weren't gold certificates. There were also gold certificates with that denomination but they have gold seals and lack the words Federal Reserve Note. Please see the question "What is the value of a 1928 US 20 dollar Federal Reserve Note?" for more information.
