If it has been copper plated, it's still just a dime.
Numismatically it's considered an altered coin and is worth only face value. However private companies create these from normal circulation coins and market them as keepsakes for a few bucks, so you might find someone willing to buy it as a novelty, that's all.
The gold plating is done by someone other than the U.S. Mint and adds absolutely no numismatic value. It's only worth as much as someone on eBay is willing to pay, but only being a 1994 dime, that won't be much.
Dimes have never been made of gold. Perhaps your coin was gold plated. There's no specific value for it, so it's only worth as much as someone will pay.
These items are solidly encased in plastic and are in a dark blue case with gold trim and an eagle on top. The 1999 set, which contains a penny, nickel, dime, quarter, and dollar, was listed on eBay today (Sept 22, 2009) for as little as $4.95 and as much as $24.95.
10 cents. It's a novelty coin.
Without seeing the coin it's not possible to say why it would appear to be copper. It could have been dipped in acid, plated with copper as a school chemistry experiment, or be what's called a "lamination error" in which the outer copper-nickel layers of a normal dime separated from the copper core. Your best bet would be to have it examined in person by a dealer or appraiser who could test its weight and look at it under a magnifier.
The US mint did not make this coin, it was done outside of the mint an is gold plated or copper plate, but it still has value for the silver under the plating. It's worth about a dollar.
If the coin is the same thickness as a regular dime it's been plated and is only worth face value. If it's thinner than a regular dime and is copper on one side only, the cupronickel cladding un-bonded from the core. This is called a lamination error and is worth around $5 or $6 Note there's no such thing as a 1967-P dime because US coins dated 1965, 1966, and 1967 don't carry mint marks.
The value of a 2006 copper dime varies depending on its condition. In some cases this dime is worth about $0.15 and might be valued at up to about $1.
If the coin is the same thickness as a normal dime, it's not copper. It's been plated or exposed to heat/chemicals that changed its color. In this case it's just a damaged dime. However, if the coin is thinner than a normal dime, it could be a lamination error. That happens when the outer cupronickel layer comes "unstuck", like taking the cookie part off an Oreo. The copper core then becomes visible. In this case it could retail for $5-6.
Because it was plated for use in jewelry or something similar. It has no added value.
No. US Dimes dated 1965 and later, were all made from a copper-clad alloy. The dime you have is gold-plated.
If there were one it would be a fabulous rarity, but all 1969 dimes were made out of copper-nickel and are only worth face value. The last silver dimes were struck in 1964. All circulation dimes after that have been made of copper-nickel. If your dime appears to be silver it's probably plated. That means it's an altered coin and is still only worth 10 cents.
It is gold plated and therefore is only worth what a normal (damaged) 1941 dime is worth, which is about $2.20 or so in scrap silver.
First weigh it ... a normal dime weighs 20268g. Then have a coin dealer check it out if different.
$2.00 for the silver under the gold, the plating destroyed any collectible value the may have had.
This did not come from the mint like that. It has to be gold plated. No collector value.
