Are there signs of use on pre-owned bullion?

Guarantees and conditions pre-owned bullion

Within our terms for pre-owned bullion, we maintain the following guarantees: 

Authenticity and quality: every product is thoroughly tested for specific gravity and purity. We guarantee that the weight and metal content are identical to newly minted precious metals. 

Buy-back guarantee: the condition of the product does not affect future resale. We offer the exact same buy-back price for pre-owned products as we do for new ones. 

Investment value: Because you pay a lower premium at the time of purchase but receive the same amount upon resale, pre-owned precious metal is a very sensible choice from an investment perspective.
