The Mint has never made gold quarters. If you have a gold quarter then it has been plated which destroys the numismatic value of the coin. Its value is 25 cents plus the value of the little bit of gold they used to plate it. Some chemicals can cause the quarter to turn different colors. This also does not enhance the value of the coin.
Twenty five cents.
Gold plated coins are novelty coins with no collectible value and are not made by the US Mint.
It may have been plated with gold but it adds nothing to the value of the coin.
Gold-plated but not gold. For one thing, a gold quarter would be worth hundreds of dollars so it would be foolish for them to be put in circulation. The gold adds nothing to the coin's worth and would in fact cost more than its value to remove.
The US Mint has never made any gold quarters, it's a novelty coin that's been plated and has no collectible value.

You are asking about a 1927 US Quarter Eagle (2-1/2 Dollar Indian Head gold coin) (KM#128). The coin is 18mm in diameter, weighs 4.18 grams and is 90% gold, giving it an AGW (Actual Gold Weight) of 0.1209 troy ounces. The is an incused (that is, cut below the surface of the coin , rather than rising above it) image of an American Indian on the front and of an eagle at rest on the back.

According to the December 7, 2010, edition of Numismatic News, a 1927 US Quarter Eagle (2-1/2 Dollar Indian Head gold coin) (KM#128) is worth US$225 in Very Fine condition, US$255 in Extremely Fine condition, US$280 in Almost Uncirculated-50 condition, US$340 in MS-60 Uncirculated condition, US$815 in MS-63 Uncirculated condition, and US$3,475 in MS-65 Uncirculated condition.
This is not a coin made by the US mint. It is probably worth only the metal value. It could be that it is only gold-plated. If it is pure gold then it is worth whatever amount of gold is in the coin.
