What is the value of a 1924 US 20 dollar gold coin which is the small coin And is this the size they came in during this time?

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.
