The only gold coin that I am aware of that was minted by the US Treasury in 1924 was the Saint-Gaudens $20 Double Eagle. This coin had a diameter of 34mm and weighed 516 grains (33,436 grams).Its value in extra-fine condition is: $1225.00.
The first trade dollars were minted in 1873. If your coin has that date on the front and the words TRADE DOLLAR and 420 GRAINS 900 FINE on the back, it's a counterfeit (replica coin). It should have been plainly marked with the stamp "COPY." If it has a spread-winged eagle and the abbreviation ONE DOL. on the back, it's a Liberty Seated dollar, not a trade dollar. In that case please see the Related Question for more details.
Assuming the coin has no mintmarks, the 1879 Morgan is a common date. For an accurate assessment of value the coin needs to be seen and graded. Most coins of this year have seen heavy use and show a lot of wear. In general retail values for F-12 (Fine) examples are $28.00-$32.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched or have been cleaned have far less value if any to a collector or dealer.
This depends on if it is a Morgan or Trade dollar.
The phrase "420 grains 900 fine" on a 1873 Liberty Dollar coin refers to its composition. It means that the coin weighs 420 grains and is made of 90% pure silver (900 fine). This was a common standard for silver coinage in the United States during that time period.
It's possible but highly unlikely. Only 1,541 trade dollars were minted in 1879 and all were struck as proofs. You most probably have a replica coin, in which case the word COPY or REPLICA should appear somewhere in the design. You could have the coin inspected by a dealer or appraiser to see if it contains any precious metal or is simply plated base metal.
All 1879 trade dollars were proofs and the entire trade dollar series is heavily counterfeited. Most likely, your coin is a counterfeit, but should be examined by someone who knows a lot about coins (good places to start are coin shops and jewelry shops) if you believe it to be genuine, but most likely it is a counterfeit. If genuine it could be worth hundreds to thousands of dollars.

"Good" condition is actually not very 'good' at all. In coin-speak a "Good" coin (capital G) is very worn, with the date, mint mark and denomination visible but most details worn off. You can check a book such as Photograde to see examples of the various conditions with names such as Poor, Good, Fine, Very Fine, AU, and so on.
