Collecting gold bullion coins is an art. Like any other art, some are good at it while some are not. True collectors of gold bullion will have a wide collection of gold coins of every kinds and nationality. A true collector will go great lengths to get a coin that he covets. Collecting coins id not for the faint hearted. Every other day there are reports of a collection of rare coins selling for hundreds of thousand of dollars. Although a store in value, gold bullion is pricey and not for those with shallow pockets.
Some coins are minted in very limited numbers. The gold American eagle coin minted on its 20th anniversary is such an example. For these limited editions, get them the first opportunity you can. Their value goes only one way; up. So many collectors are usually after them and obeying the laws and demand and supply, their value rises year after year. This is true for any other rare coin. It is better to get it and keep it if it is rare. One collector or another is always looking for rare coins which you will happen to have in your collection.
Gold bullion is not the only precious thing that is valuable. Silver dollars are sometimes very valuable too. It is better to have a silver dollar of 19th century mint than a gold coin of the late 90s. This is because value of precious coins mainly depends on the rarity of the coin. If you see a silver dollar, better pick it up.
