There has been a question among gold owners as to why they shouldn't invest in gold or silver bars rather than coins. oins have always provided a stronger resale value because of the added collectibility factor. Why Gold Coins Over Other Forms of Gold? The pedigree gold coins are a form of pure gold. This sounds obvious, but these coins will rise as the base value of gold as a commodity rises. And as we have seen in past markets, the likelihood of this to happen in the short/medium term is very high. Gold and silver coins not only give you a superb vehicle for owning precious metals but they have a sub-market within gold; the collectors market is huge.
