Guarantee of Authenticity

Authenticity Guarantee

Aventine Coins & Bullion is a registered New Zealand business. We guarantee the authenticity of every item we sell. 

Authenticity of Coins and Banknotes

We expressly guarantee that all coins and banknotes are genuine. In the rare event that we offer a reproduction item, this is clearly stated in its description.

Contemporary Imitations and Fourrées

Our return and refund policy expressly protects you against counterfeits/forgeries.

With ancient coins, we may occasionally offer fourrées. A fourrée is a contemporary counterfeit struck from a base-metal core (typically copper or bronze) and plated with a precious metal such as gold or silver to pass as a higher denomination. These imitations were made during the period in which the genuine coins circulated, and are themselves collectable historical artefacts.

Where a coin we offer is a fourrée or other contemporary imitation, this is always stated explicitly in its description. Should an item we sold be determined to be a fourrée or contemporary imitation when we did not describe it as such, we will offer appropriate compensation options.

Forgeries and Misattribution

If any item purchased from Aventine is later proven — with certainty, by an independent and recognised third-party authority such as NGC, PCGS, PMG, or another suitably qualified specialist — to be a forgery, significantly misattributed, or to have significant faults not reasonably visible in the photographs or otherwise disclosed, we will arrange the return of the item at our expense and provide a full refund of all charges paid to us. Refunds are issued after we receive and inspect the returned item in the same, unaltered condition as when it was sold.

A Note on Descriptions and Images

We endeavour to present every item as accurately as possible. Minor differences in colour or appearance may arise from lighting, photography, and individual monitor settings.

Any descriptions, grades, and comments represent Aventine's opinion at the time of sale and may differ from the views of other experts, or shift over time as scholarly consensus evolves.
