Bullion coins
- Valued mainly for their gold content at the live price.
- Struck in large numbers every year.
- Made to high standards, but not individually graded.
- May carry tiny marks from production or handling.
- The simplest, lowest cost way to own gold.
Certified coins
- Examined, authenticated and graded by NGC or PCGS.
- Given a grade on the 1 to 70 Sheldon scale.
- Sealed in a tamper evident holder showing the grade, year and a certification number.
- Valued on grade, rarity and collector demand as well as gold.
Why grading changes the price
Coins of the same year vary in condition. Grading turns “this looks nice” into an agreed, independent number. At the very top, the difference between MS69 and MS70 can change a coin’s price dramatically, because perfect coins are scarce. More in MS69 vs MS70.

The common misunderstanding
A certified coin does not contain more gold. If the gold price doubles, a bullion coin and a certified coin gain the same amount of metal value. The certified coin’s extra value sits on top and moves with collector demand, which can rise or fall independently of gold.
Which to choose
- Choose bullion if your goal is to own gold as efficiently as possible.
- Choose certified if you value verified condition, scarcity and the enjoyment of collecting.

Questions people ask
Does a certified coin contain more gold?
No. It contains the same gold as its bullion equivalent.
Why are certified coins more expensive?
You pay for independent authentication, a verified grade and scarcity at that grade.
Can I get my own coins certified?
Yes, by submitting them to NGC or PCGS, though the fees rarely make sense for common bullion coins.
Do certified coins follow the gold price?
Their metal value does, but their collector premium moves independently.
