1 oz gold coin vs 1 oz gold bar
Both hold exactly 31.1035 grams of gold — one troy ounce. The metal content is identical. The premium, packaging, recognizability, and resale dynamics are what separate them — and for most buyers, those differences matter more than people realize going in. This guide compares them side by side and helps you decide which makes sense for your situation.
Side-by-side specifications
The premium difference in real money
At spot gold price of $3,200 per ounce, here is what you typically pay:
- PAMP Suisse 1 oz bar: approximately $3,232-3,264 (1-2% premium = $32-64 over spot)
- 1 oz American Gold Eagle: approximately $3,296-3,360 (3-5% premium = $96-160 over spot)
- 1 oz Canadian Maple Leaf: approximately $3,264-3,328 (2-4% premium = $64-128 over spot)
The difference between bar and coin can be $64-100+ per ounce at current prices. But here is what most guides miss: resale premium matters too.
A bar resells at 0.5-1% over spot. A coin resells at 2-3% over spot. If you buy an Eagle at 4% ($3,328) and sell at 3% ($3,296), your spread cost was $32. If you buy a PAMP bar at 1.5% ($3,248) and sell at 0.5% ($3,216), spread cost was also $32. So the spread cost can be similar despite very different buy premiums.
Key insight: compare buy-sell spread, not just buy premium.
When a coin wins
- Wider recognition — any dealer worldwide knows an Eagle, Britannia, or Maple Leaf on sight
- Faster resale — no purity verification needed, just visual authentication
- Legal tender status — some sovereign coins have CGT exemptions (UK Britannia for UK buyers)
- Easier for non-specialist buyers — clearer to compare, quote, and price
- Gifting — a coin in a presentation box is more appropriate as a gift than a bar
When a bar wins
- Lower premium — if you are buying multiple ounces, the premium saving compounds (10 oz: $640-1,000 less than equivalent coins)
- Simpler metal exposure — no numismatic value mixed in, purely a metal play
- Stackable — standard LBMA bar dimensions stack neatly
- Institutional format — if you ever want to vault or sell to a refiner, bars are the standard wholesale format
- Lower storage cost per gram — some vault services charge by number of pieces, making fewer larger bars more efficient
How to make the decision
Use this framework to choose what works for your situation:
- If this is your first purchase: coin — the recognizability makes buying and any future resale less stressful
- If you are buying multiple ounces at once: bar — the premium saving is real money at scale
- If you are in the UK: Britannia — CGT exemption makes it the obvious coin
- If resale comfort matters more than cost efficiency: coin
- If you are building a position to hold long-term and resale is 5+ years away: either works; optimize on premium
