Welcome to Aventine Numismatics, one of New Zealand's leading coin dealers, where history and investment converge. Specializing in rare and collectible coins, banknotes, and bullion, we offer a unique and diverse range of products to satisfy the needs of collectors and investors.

What sets us apart in the market is our name being synonymous with classical numismatic rarities for collectors while dealing in bullion for those looking to invest and buy gold bullion in NZ.

For those looking to sell, we actively buy gold coins and typically offer the following three options for items we are interested in.

1] Consignment Sale: We can sell your coins or bullion on your behalf. This includes a signed sales agreement and an itemized list. While we charge a commission upon a successful sale, you can expect a higher return.

2] Purchase: For eligible items, we can offer a timed settlement within 21 days of the items being received. We are required to abide by the New Zealand Ministry of Justice's legislation for a holding period for new goods. The bonus of this option would be a far more competitive price to be settled upon the 21 days. 

3] Immediate Cash Sale: For those seeking an urgent sale, we can offer an option to purchase your items outright on the spot.

Every piece of gold and silver bullion bought from us is required to undergo non-destructive metal testing to ensure authenticity.

Whether you're in the market to buy gold bullion in NZ or seeking rare gold coins, Aventine Numismatics is your trusted partner. Contact Us for personalised assistance with any of your needs.
