You can usually get a better deal on a larger order. Credit Suisse and Pamp SA is the major player in the U.S. market. The bars come with a certificate of authenticity and sell for the price of the gold plus a small premium. The U.S. Silver Eagle, Canadian Silver Maple Leaf, and Australian Kookaburra are the most popular one ounce silver coins. You can also buy old U.S. silver coins.
Silver is considerably less expensive than gold, so the entry bar is lower.
This makes acquiring silver coins more attractive for the small investor. Platinum coins, on the other hand, will be more than gold. The Australian Koala, Canadian Platinum Maple, and the U.S. Platinum Eagle are the most popular coins. Both platinum and silver are available in bar form, but the coins are easier to resell. The collectible market, like all others, follows the law of supply and demand.
