Buying silver coins is an excellent investment activity as well as pleasurable due to the aesthetic qualities of the coins.
Such coins as the American Silver Eagle, the Canadian Silver Maple Leaf and the Chinese Panda are just a few examples of such silver coins worth buying and keeping.
Silver is on the rise and currently reaching the peaks it did in 1984 so is a worth while portfolio to add to your investment.
When buying silver coins watch out for such coins as the 1879 Trade T$1 TRADE DOLLARS, PROOF PCGS or the 1857-S SSCA GF $20 DOUBLE EAGLES - CORONET, TYPE 1 PCGS MS-65, as examples of rare coins. There are many rare coins and some Silver Morgans are another example of rare silver coins.
These are worth many times the face value and silver value due to their rarity.
When buying silver coins also ensure that you pick a reputable dealer who is prepared to authenticate the coins you buy. A certificate should accompany any rare or proof coins bought.
Silver coins are generally easier and cheaper to buy than gold coins as silver is a lot less per ounce. But silver is rising faster than gold in value so should be seriously considered as a future long term buy.
Perhaps more important is doing your due diligence and study on silver coins and dealers. Making sure you understand the various coins and how they are graded. Who the current dealers are, what they offer and what guarantees they offer.
Doing the above you are sure to enjoy the fascinating and rewarding activity of buying silver coins!
