Oftentimes, the listed value on the face of a coin is different than its actual value. As such, antique coin collecting, buying, and selling is a fairly popular industry for businessmen and hobbyists. Old nickels, pennies, or even silver dollars often contain or are plated with actual nickel, copper, or silver metal making them much more valuable. It can be difficult to determine the coin values actual worth, so speaking with an expert or looking values up online are better options than simply going and spending the coin for face value.
Along with coins, the value of precious metals can fluctuate over time. Historically, precious metals have always held their value over centuries and as such are an excellent investment. That is how companies such as “Cash For Gold” and others earn so much money; they are able to liquidate people’s unwanted jewelry to give them immediate money, and then they (the company) can save up gold (or other metals) and sell them at a premium rate.
If you have any unwanted gold jewelry or antique coins that may contain precious metal, such as gold coins, then to make sure you are getting a good value for re-sale, check the going rate for such items before making a transaction. The worth of such items can be found online from a variety of sources (indexes as well as commercial rates), as well as speaking with a professional in the industry over the phone or in a nearby shop.
