Please check your bill's date and post a new, separate question. A bank name would appear on a 1929 National Bank Note. 1928-series bills were either Federal Reserve Notes or gold certificates.
There are two different kinds of 1929 $20 bills. One type of 1929 $20 bill is the Federal Reserve Bank Note. These 1929 twenty dollar bills will generally not be worth more than a few times face value due to their large printing numbers. 1929 $20 bills that are Federal Reserve Bank Notes will say Federal Reserve Bank of Boston, New York, Philadelphia, Cleveland, Richmond, Atlanta, Chicago, St. Louis, Minneapolis, Kansas City, Dallas, or San Francisco. If one of these 1929 $20 bills has a star symbol in the serial number it will be worth much more than a few times face value. The other kind of 1929 twenty dollar bill is the 1929 national bank note. The 1929 national banknotes can be worth a few dollars over face value to several hundred dollars. The value all depends on which bank issued the notes. These 1929 $20 bills will say National Bank somewhere in the title on the left hand side of the note.

The value of a 24k gold bank note primarily depends on the current market price of gold and its collectible appeal. As of October 2023, the price of gold is approximately $60 per gram, which would place the intrinsic value of a 54-gram note at around $3,240. However, if the note has collectible features or historical significance, its value could be higher. It's advisable to consult with a numismatic expert or appraiser for an accurate valuation.
In perfect condition $750 to $1200. Thanks! Also, what would be the value of a note from the Central Bank of China (Shanghai, 1930).

No US $20 bills were dated 1920. A brown seal most likely indicates you have a 1929 National Currency Note. If so, values depend on which bank distributed the bill. Please see the question "What is the value of a 1929 US 20 dollar bill?" for more information.
To clear things up, the bill was actually printed in Washington. Boston is the location of the Federal Reserve Bank that distributed it. Please see the question "What is the value of a 1929 US 20 dollar Federal Reserve Note?" for more details.
This is not something that was made at the mint. It is a novelty item. They are worth nothing to collectors. Gold plating adds no value to the item.
No - UK currency is valued against gold. For example - the pledge on UK £5.00 banknotes reads 'I promise to pay the bearer on demand the sum of five pounds'. The 'pound' in the pledge is not a unit of weight but the monetary value of the note in gold. It simply means that you (theoretically) could take a £5.00 note into the Bank of England in London - and exchange it for an equivalent quantity of gold at the prevailing rate.
The Greenville Texas bank Note, 8581, you speak of is worth $75-$150 depending on condition.
