How Gold Coins Are Checked
A bullion coin's authenticity is assessed using more than its colour. Providers may look at denomination, dimensions, weight, design details and other suitable checks.

About how gold coins are checked
Official coin specifications help identify mismatches, but different coin families have different purities and gross weights. A Krugerrand and a modern Britannia can each contain an ounce of fine gold while being different overall weights.
Prices, checks & considerations
Keep coins in their existing holders where practical and avoid cleaning them before an appointment. If an item might be collectible, ask whether the provider can assess that feature or only bullion content.

Frequently asked questions
Does a gold-coloured coin prove it is genuine?
No. Appearance alone is insufficient; professional verification may be necessary.
Can weighing a coin alone authenticate it?
No. Correct weight is useful but not conclusive, and the expected gross weight depends on coin type and alloy.
