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.
If it has a green seal, it's worth $12 to $15.
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.
$60 if worn, up to double that if in nearly-new condition.
The only $20 bills printed in the 1934 series were Federal Reserve Notes so I'm assuming that's what you have. In worn condition most of these retail for about $22 despite their age. In better shape the retail price depends on what series letter, if any, is next to the date. Series D bill retail for up to $30 in excellent condition, Series C up to $28, and the rest up to $24. FWIW, the last $20 silver certificates were issued in 1891. The wording "will pay to bearer on demand" is found on older FRN's but was removed from later series.
There were no 1928A gold certificates printed, only 1928 with no series letter. (Series letters, when present, are next to the date, not beside the serial number or elsewhere.) If you have a plain 1928 bill, its value would range from $250 in worn condition to about $750 if it's only slightly worn.
If it has a green seal, it's worth $12 to $15.

How much is a .999 fine silver coin worth Ten dollar redeemable cash value .999 fine silver limited edition collector's series ...
1928 US five-dollar bills with red seals were common in circulation. For this reason, they only command about $7, unless they are in mint condition with no folds, then they would be able to get more.
All Red Seal U.S. notes carry that motto so it's not a distinguishing feature. Depending on its condition and whether it has a series letter (a single character) right after the date, it could be worth anywhere from face value to about $30.

It would be helpful to know the Country, Date and Condition of the note in question. If you are talking about a US $10 silver certificate, you might also look for a little "Series" letter next to the date. With that someone might have an idea what sort of 10 dollar bill you are talking about. Otherwise it is hard to make any sense of your question.
It really depends on the series, but the small sized series look very similar to a normal US dollar bill only rather than having a green serial number it is blue. It also has a blue seal, says "Silver certificate" at the top, and rather than saying "X Dollar(s)" it says "X Silver Dollar(s) Payable to Bearer on demand" Earlier silver certificates will look different. For images just Google "Silver Certificate" and look at the different types.
