To clarify things, there is no 1929 "G" series - G is simply the letter code for the Chicago Federal Reserve district. All current $1 and $2 bills and old higher-value bills have similar letters indicating the district that distributed them. Of course, the bills aren't actually printed in the issuing district - they're printed by the Bureau of Engraving and Printing in Washington (and since 1991, Fort Worth) with the name and letter of the issuing district added.
Your bill is actually called a Federal Reserve Note, like modern $20 bills, rather than "a bank note of Chicago". Chicago is simply the Federal Reserve District location that distributed the bill. Please see the question "What is the value of a 1928 US 20 dollar Federal Reserve Note?" for more information.
A denomination is needed. Please look for questions in the form "What is the value of a 1928 A US [denomination] dollar Federal Reserve Note?" for specific information.
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.

Grover Cleveland appeared on two different $20 bills, both printed in the 1914 series. There's more information at the question "What is the value of a 1914 US 20 dollar Federal Reserve Note?" For clarity, the bill was actually printed in Washington and was distributed by the Richmond Federal Reserve district.
To clear things up, the bill wasn't made in Chicago. It was printed in Washington for distribution through the Chicago Federal Reserve District. Please see the question "What is the value of a 1934 A 10 dollar Federal Reserve Note?" for values and other information.
It's still worth one dollar.
