How to Verify a Gold or Silver Dealer's Price Is Fair (Premium Calculator Guide)

The short answer: a fair premium is the dealer's asking price minus the live spot price, divided by the live spot price. For common gold coins, 2–5% over spot is normal; for silver coins, 8–20% is normal because silver's lower unit value means fixed minting/handling costs are a bigger percentage. Anything materially above that range for a standard bullion product is worth questioning.

What Is a Dealer Premium?

Every physical metal purchase costs more than the spot price you see quoted on financial sites. That markup — the premium — covers minting, distribution, dealer margin, and market demand. It is not a scam; it is the real cost of converting a spot-price number into a physical object in your hand. The question isn't whether there's a premium, it's whether the premium is reasonable.

How to Calculate Premium Yourself

The formula: premium % = (dealer price − spot price) ÷ spot price × 100

Example: gold spot is $2,400/oz. A dealer lists a 1 oz American Eagle at $2,472. Premium = ($2,472 − $2,400) ÷ $2,400 = 3%. That's within the normal range for a well-known government-minted coin.

Typical Premium Ranges by Product

Product type	Typical premium over spot
Gold bars (1oz+, generic mints)	1–3%
Gold government coins (Eagle, Maple, Krugerrand)	3–6%
Silver bars (10oz+)	5–10%
Silver government coins	10–20%
Fractional gold (under 1/10 oz)	8–20%+
Numismatic/collectible coins	Highly variable — value is not premium-based

Why Silver Premiums Look So Much Higher Than Gold's

It's not that silver dealers are greedier — it's that minting and handling a $30 coin costs roughly the same in absolute dollars as minting a $2,400 gold coin. That fixed cost is a much larger percentage of a low-value item. Don't compare silver and gold premiums on the same percentage scale; compare each metal against its own typical range.

Red Flags That Signal an Unfair Price

• Premium more than double the typical range for that product type with no clear reason (limited mintage, rare date)
• "Sale" pricing that's actually above the normal premium range once you check current spot
• No clear breakdown of spot price vs. premium in the listing
• Pressure tactics ("price locked for 10 minutes") on a standard bullion product, not a numismatic rarity

Checking Premiums Before You Buy

BullionKeeper's Verify a Deal tool does this calculation automatically — paste in a dealer's quoted price and it compares it against live spot in your currency, showing you the exact premium percentage before you commit. It's the same check described above, just without doing the math by hand while a "limited time offer" timer counts down.

Summary

• Premium = (dealer price − spot) ÷ spot, expressed as a percentage
• Gold coins: 3–6% is normal. Silver coins: 10–20% is normal.
• Compare against the product type's typical range, not a flat number
• Always check live spot at the moment of purchase, not a stale number from earlier that day
