Market Basics
Precious metals prices are quoted per troy ounce and driven by global supply/demand, currency strength, and macroeconomic factors. Dealers quote spot (the live wholesale price) plus/minus a premium (or discount) reflecting minting costs, scarcity, and demand.
What affects spot & premiums?
- Mint & fabrication: Coins generally carry higher premiums than bars.
- Supply/demand: Retail shortages or dealer buy-backs can widen spreads.
- Liquidity: Popular sovereign coins usually sell faster and closer to spot.
- Condition & rarity: Collector-grade coins can price far above melt value.
Metal Guides
Gold (Au)
The benchmark store of value with deep liquidity. Common purity for bullion coins is 22k (0.9167) or 24k (0.999/0.9999). Popular issues include American Eagles, Canadian Maple Leafs, Krugerrands, and Britannias.
- Strengths: High liquidity, global recognition, strong jewelry/central bank demand.
- Consider: Higher premiums than silver; 24k scratches more easily.
Silver (Ag)
Affordable entry metal with industrial demand. Bullion coins/bars typically .999 fine. Popular coins: American Silver Eagle, Maple Leaf, Philharmonic, Britannia.
- Strengths: Lower unit cost, flexible for incremental stacking.
- Consider: Bulkier storage; premiums can be volatile in retail shortages.
Platinum (Pt)
Scarcer than gold with significant automotive and industrial use. Common fineness is .9995. Popular coins: American Platinum Eagle, Canadian Maple Leaf, Britannia.
- Strengths: Industrial diversification, historically cyclical opportunities.
- Consider: Thinner dealer networks than gold/silver; wider spreads.
Palladium (Pd)
Highly industrial with tight supply/demand dynamics. Fineness typically .9995. Coins include Canadian Maple Leaf and American Palladium Eagle.
- Strengths: Strong industrial demand; potential scarcity premium.
- Consider: Higher volatility; spreads can be wider than gold/silver.
Bullion vs. Numismatic
| Aspect | Bullion | Numismatic (Collectible) |
|---|---|---|
| Primary driver | Metal value (spot + premium) | Rarity, grade, demand, provenance |
| Volatility | Tracks metal price | Can decouple from spot |
| Liquidity | Very liquid at dealers | Best via specialists/auctions |
| Storage/handling | Less sensitive | Careful handling; graded holders |
| Examples | ASEs, Maples, bars | Morgans, Pre-33 US, rare types |
Formats & Common Weights
- Coins: Government-minted, face value, usually the most liquid.
- Rounds: Private-minted, no face value, typically lower premiums than coins.
- Bars/Ingots: Efficient for larger amounts; popular in 1 oz, 10 oz, 100 oz (silver), and kilo sizes.
Standard Weights
- Fractional: 1/20 oz, 1/10 oz, 1/4 oz, 1/2 oz
- 1 troy oz (31.1035 g)
- 10 troy oz, 100 troy oz (silver)
- 1 kg (32.15 troy oz)
Note: A troy ounce differs from an avoirdupois ounce used in everyday goods.
Authentication & Grading
Basic Checks
- Dimensions & weight: Compare to mint specs with a caliper and precise scale.
- Magnetism: Gold/silver/platinum/palladium are non-magnetic—beware strong attraction.
- Sound test: Silver/gold coins have a distinct ring; avoid if uncertain.
- Specific gravity: Density checks can flag plated/counterfeit items.
- Professional verification: XRF analysis and dealer inspection provide certainty.
Third-Party Grading
Numismatic coins are often certified and encapsulated by services such as PCGS or NGC, with grades on the Sheldon scale (1–70). For modern bullion, grading is optional unless a special issue/finish.
Storage & Care
- Environment: Cool, dry, low-humidity. Avoid PVC flips; use Mylar or inert holders.
- Handling: Handle by edges; cotton or nitrile gloves for proofs/uncirculated coins.
- Security: Consider a home safe (fire/water rated) and/or professional vaulting.
- Documentation: Keep receipts, certificates, photos, and an updated inventory.
- Insurance: Schedule items on homeowner’s policy or specialized collectibles insurance.
Buying & Selling
Buying Tips
- Define purpose: stacking (bullion) vs. collecting (numismatics).
- Favor recognizable mints/series for liquidity.
- Compare premiums and dealer buy-back policies.
- Watch for cleaned/damaged coins if collecting.
- Verify authenticity—especially for secondary market bars/rounds.
Selling Tips
- Know melt value and recent realized prices for similar items.
- Maintain original packaging/certificates for proofs and limited issues.
- Shop bids among reputable dealers; consider consignment or auction for rare pieces.
Spreads & Fees
The spread is the difference between dealer sell and buy prices. Spreads tighten for highly liquid items and widen for niche/low-demand products or when markets are stressed.
Tax Considerations
Tax treatment depends on jurisdiction and product type. In many places, precious metals may be subject to sales tax and capital gains tax when sold at a profit. Keep accurate records of purchase dates, costs, and proceeds. Consult a qualified tax professional for guidance specific to your situation.

Frequently Asked Questions
Are coins better than bars?
Coins from major sovereign mints are typically more liquid and easier to sell; bars often have lower premiums for larger purchases. Choose based on budget, storage, and exit strategy.
What does “.9999 fine” mean?
It indicates 99.99% purity. Higher fineness usually commands a slight premium, especially for gold.
Should I grade modern bullion coins?
Only if the coin has special finishes, low mintages, or you’re targeting collectors. For pure stacking, raw coins are usually more cost-effective.
How do I calculate melt value?
Multiply the coin/bar weight by fineness to get pure metal weight, then multiply by current spot price. Example: 1 oz gold coin at .9167 fineness ≈ 0.9167 troy oz of pure gold × spot.
What’s the best way to store my collection?
Use inert holders, keep humidity low, secure items in a rated safe or professional vault, and maintain an inventory with photos for insurance.
