The U.S. never minted dimes out of gold. In any case, just like today the price of gold was a lot higher than the price of silver and a dime-sized coin struck from gold would have been worth much more than $1.00.
The coin you have has either been plated for use in jewelry, or was exposed to some chemical or heat that oxidized its silver. The bad news is that whatever happened has reduced the coin's value as a collectible. Untouched, it might have retailed for somewhere between $10 and $30. But as a damaged coin it would be worth half that or less.
An 1877 gold dime is a rare and valuable coin. Its worth can vary depending on its condition, rarity, and current market demand, but it could be worth hundreds or even thousands of dollars to a collector or investor. It's best to have the coin appraised by a professional to get an accurate valuation.

it depends on how old it is.
