• Silver Bars — Ranging from 1 oz to 100 oz, from brands like Engelhard, Johnson Matthey, Sunshine Minting, and more.

Platinum

Platinum products are rarer than gold or silver on the market:

• Platinum Coins — American Platinum Eagles, Canadian Platinum Maple Leafs, and other government-issued platinum coins.
• Platinum Bars — Available in smaller sizes (1 oz, 10 oz) from major mints.

Product Types

Bullion Bars

Bars are rectangular pieces of refined precious metal, typically stamped with the manufacturer's mark, metal purity, and weight. They come in standard sizes:

• Gold Bars — 1 g, 5 g, 10 g, 1 oz, 10 oz, 1 kg
• Silver Bars — 1 oz, 5 oz, 10 oz, 1 kg, 100 oz
• Platinum Bars — 1 oz, 10 oz

Bars generally carry lower premiums than coins, making them popular with investors focused on accumulating metal at the lowest cost per ounce.

Bullion Coins

Government-issued coins made of precious metals. These carry a legal tender face value (though their metal content is worth far more) and are produced by national mints around the world. Popular series include:

• American Eagles (Gold, Silver, Platinum)
• Canadian Maple Leafs (Gold, Silver, Platinum, Palladium)
• Austrian Philharmonics (Gold, Silver)
• British Britannias (Gold, Silver)
• Australian Kangaroos (Gold, Silver)

Collectible and Numismatic Coins

Coins valued primarily for their rarity, historical significance, condition, or aesthetic appeal rather than their metal content:

• Key Date Coins — Coins from years with particularly low mintages that are highly sought after by collectors.
• Error Coins — Coins with minting errors (double dies, off-center strikes, etc.) that make them unique and valuable.
• Commemorative Coins — Special issues marking historical events, anniversaries, or notable figures.
• Ancient Coins — Coins from ancient civilizations — Greek, Roman, Byzantine, and others.
• World Coins — Coins from countries around the globe, spanning centuries of history.

Graded and Certified Coins

Coins that have been professionally evaluated and encapsulated by a third-party grading service. The two most respected services are:

• PCGS (Professional Coin Grading Service)
• NGC (Numismatic Guaranty Company)

Graded coins receive a numeric grade on the Sheldon scale (1–70), with 70 being a perfect specimen. Common grade ranges include:

Graded coins are sealed in tamper-evident plastic holders (slabs) with a label showing the grade, certification number, and other details. They typically command higher premiums due to the certainty of their condition.

Browsing Categories

You can browse categories in several ways:

1. Navigation menu — Use the Categories dropdown in the top navigation bar to access any category directly.
2. Homepage shortcuts — The homepage features quick links to the most popular categories.
3. Breadcrumb navigation — When viewing a category page, breadcrumbs at the top show where you are in the hierarchy and let you navigate up.
4. Filters — Within any category, use sidebar filters to narrow results by metal type, price range, year, mint, grade, and more.

Tips for Category Shopping

• Start broad, then filter — If you're not sure exactly what you want, start with a broad category like "Gold Coins" and use filters to narrow your results.
• Check subcategories — Major categories have subcategories that can help you find specific products faster.
• Use the metal price pages — Before shopping a specific metal, visit its price page to check current market conditions and use the calculator to estimate fair value for the weight you're considering.
