An Indian head nickel that is 24 karat gold layered, with no date, mint mark, and has been circulated is worth between $0.05 and $0.30 (as of 2013). Although they are rare, they are not worth a lot of money.

The pricing of the coin truly depends on the condition of the coin. If it has been circulated then it greatly reduces the value of the coin due to the natural wear of being circulated. The best thing to do is to take it to a coin dealer to examine and appraise. Only then will you get a true answer and a price to go by.
No, if not iron, cobalt or nickel inside

Yes it can, if the silver has nickel in it which most silver will have some in it. You are best to use 14 Karat or higher gold (not white gold) or titanium. Theses metals have no nickel and should cure the problem. Remember even high grade surgical steel has nickel.
No. US nickels have never contained any gold. For one thing, even when the price of gold was much lower a gold coin the size of a US nickel would have been worth several dollars; today it would be worth hundreds.
It means 18 karat heavy gold electroplate. It is not solid gold. 18 karat gold is 75% gold blended with other cheaper metals, usually for durability. The words "plated," "layered," or "clad" indicate a thin outer coating of gold over a base metal. There is normally very little actual gold.
Gold purity is measured in karats (known as "carats" in countries of the British Commonwealth) and refers to the amount of pure gold present in the jewelry. Twenty-four-karat gold is considered to be pure gold, or 99.9% pure to be exact. Dividing the karat unit by 24 will provide the percent of pure gold in the jewelry. Thus, if you are wondering how much gold is in a 9-karat piece of jewelry, divide 9 by 24 to get 37.5%. The metal is 37.5% gold and the remaining 62.5% is likely copper, silver, nickel, or other metals.
24 karat is pure gold. 32 karat is impossible.
