The U.S. has never made a 5-cent gold coin. If your coin has a large V on the back and the word CENTS near the bottom, it's a standard Liberty nickel that was plated.
When the denomination first was issued in 1883, crooks quickly noticed that the word CENTS was not part of the original design. They gold-plated them and passed them off as a "new design" $5 gold piece. These became known as "racketeer nickels" and are now considered to be quite collectible despite being fakes. The Mint soon changed the design to add the word CENTS, and the fakery stopped.
If your nickel is dated 1888 and not 1883, it may have been a late attempt at making a racketeer nickel, or simply something that was plated for use in a necklace or other jewelry. In that case it's unlikely to be worth more than a small amount above face value because it's technically an altered coin.
The coin (assuming it is a US coin) is only worth 1 cent. Either the coin was chemically treated to make it look gold or it was gold plated. Either way, it is not worth any more than one cent.
That coin is still legal tender in Ireland, so it is just worth ten cent.
An 1888 5 dollar gold coin can be worth anywhere from $400.00 upwards to one grand. It really depends on the circulation of the coin and its overall condition.
If the coin is a Lincoln cent dated 1964 it may look like gold or have been gold plated but the US Mint has never made a gold one cent coin.
$1 - $100 depending on the coin if it is a $100 coin it is worth $100 if it is a 50 cent coin.
Being gold plated removes its numismatic value. The coin is worth 50 cents and the plating less than one cent.
It likely just looks gold colored, the US Mint has never made a coin one cent coin.
I will put a value of $420.00 retail on this coin. That's the value of a Extremely Fine graded Quarter Eagle dated 1888
The D after the 5 means dollars not cents, the US has never made a five cent gold coin. Take it to a coin dealer for an idea if value.
The U.S. has never made a gold one cent coin. Post a new question with a date.
One cent. The U.S. does not make gold pennies. Your coin has either been plated for use in jewelry, or the copper coating has reacted a bit with the zinc core. The latter can cause a goldish tint. Gold currently sells for about $1000 an ounce. A cent weighs around 1/12 of an ounce so a penny made of gold would contain about $80 worth of gold, not a sensible way to make that coin. Alternately, one cent's worth of gold would result in a coin so small you'd need a magnifying glass to see it, LOL!
$450 to $500 regardless of mint mark, due to its metal content.
