All forms of Gold and Silver are good candidates for investment. But coins in particular offer particular value; on the one hand they have intrinsic value based on their precious metal content, in addition to this depending on the coin you buy they can have additional value basd on their condition and rarity.

The most important thing is to do your research to understand which coins are increasing in value (google can help here!) and then head over to ebay where you wil find a constantly updated selection of Gold Coins.
