If a coin is clad in 24-karat gold, most likely the coin itself is NOT "solid gold"; the majority of the material may be copper, nickel, or manganese (or some alloy using two or more non-precious metals), with only the exterior surfaces being plated in 24-karat gold. This is the method by which many novelty coins are produced (i. e., ones made by companies not affiliated with a nation's treasury department, like the U. S. Mint as an example). Bullion coins, such as the American Eagle or American Buffalo, the South African Krugerrand, and the Canadian Maple Leaf, are generally 0.9993 pure gold, the metal being consistent through the coin. These coins are always marked as to their weight ("1 ounce fine gold", or "1/2 ounce", etc.), and with the value of gold currently at $1580.00 US per ounce (July 2011), they aren't likely to be mistaken for novelty items advertised on TV at $40 or $50 each.
NO
The US never made $2.00 gold coins. Please look at the coin again
Yes a coin could be struck in 10k gold, but the U.S. has never made one.
Gold plating a coin is legal but is considered an "altered" coin, and cannot be used or put into circulation.
No.
Yes, gold powder is still considered a solid substance. It may have a different physical state compared to a solid bar of gold, but gold particles in powder form retain their solid properties.
No, a gold clad coin is not pure gold. It is typically a thinly plated layer of gold over a base metal. The thickness of the gold layer can vary, but the majority of the coin is made up of the base metal.
Depends on what the coin is made out of. The coin has absolutely no collector value because it wasn't made by the US Mint. Any value comes from the material the coin was made out of. If the coin was gold plated, it would be worth a couple cents at most. If the coin was solid gold, it would be worth the value of the gold, but no more.
The coin is either gold plated or just looks gold. Either way it is not solid gold. It is only worth 5 cents.
Rolled gold plate is not solid gold; it is a composite material made by pressure bonding a thin layer of gold to a base metal. The gold layer is usually thicker than gold-plated items, making it more durable and valuable. However, it is not considered solid gold and may not have the same value as pure gold items.
Gold is a solid at Room temperature and pressure.
It is only gold plated. This adds no value to the coin. It is considered an altered coin and is worth 25 cents.
