Gold-plated, but not gold. The plating destroyed any collectible value the coin may have had, but 1923 is a common date for silver dollars so it's at least worth its melt value, around $14-15 as of 07/2010.
Remember that gold double eagles minted at the same time were similar in size and worth over 20 times as much.
No one dollar gold coins were struck in 1923
If the coin is a real Morgan or Peace dollar. The value is just for the silver, about $20.00.
Please check your bill again and post a new, separate question. No $10,0000 bills were printed with a 1923 date, and the last gold certificates of that denomination were made in 1900.
Please go back and look again. There are no U.S. $2.50 coins with that date.
Look at the date again. No $5 gold coins were struck in 1923.

The US stopped making regular circulation $1 gold coins in 1889. The only $1 gold pieces issued after that were commemoratives sold to collectors, and none were minted in 1923.If you have a large (38.1 mm) coin with an eagle and the word PEACE on the back, you have a silver dollar that was plated with a small amount of gold. The plating destroyed any collectors' value so it's only worth the silver it contains, about $10 as of 11/2009.

It's made of silver and was plated with gold for use in jewelry or something similar. That means it's an altered coin worth only its metal content, about $10 at the price of silver in 03/2009.
It's only gold plated, which pretty much destroys any collector value it may have had. Value for silver it contains is about $13
There is no such thing as a mint-produced "golden" Peace Dollar. Such things are genuine Peace Dollars which have been damaged by someone plating them with gold. The gold content isn't high enough to add in any precious metal values and the coin has been damaged to any collector.
Look at the coin again and post new question, the US did not make any one dollar gold coins dated 1923.
