How to Participate in a Downies Collectables Auction (For Bidders)

Taking part in a collector item auction may seem complex at first, but the process is surprisingly straightforward. Each Downies auction is carefully structured to ensure fairness, transparency and an enjoyable experience for collectors at every level. Our auctions will feature a range of collectables across a wide range of categories, including:


You can participate in several ways. Many collectors bid through our Live Bidding Platform, following the auction in real time from anywhere in the world. Others prefer to attend the auction in person, place bids by phone, or submit absentee bids ahead of time.

Whichever method you choose, the process begins with the auction catalogue.

  1. Step 1: Register as a Bidder with Downies

    Before bidding, collectors must register with Downies and obtain a bidder number. This ensures the auction runs smoothly and that each bid can be clearly attributed.

    Registration is quick and straightforward. Once approved, you will be able to participate in the auction either online or in person.

  2. Step 2: Browse the Downies Auction Catalogue and Lots

    Every Downies auction is accompanied by a detailed catalogue listing all available lots. This catalogue is the collector's roadmap to the sale.

    Each lot includes a description prepared by our numismatic specialists, outlining key details. Using the example of coins, you can expect to see:

    • Coin date
    • Denomination
    • Condition
    • Historical significance

    High-quality images allow collectors to examine each piece closely before bidding.

    Expert tip: Many bidders begin by identifying the lots that fit their collection goals, noting the estimate ranges and planning their bidding strategy accordingly.

  3. Step 3: Inspect Items During Pre-Auction Viewing

    Whenever possible, collectors are encouraged to inspect lots during the pre-auction viewing period. This provides the opportunity to examine coins and other collectables firsthand and appreciate their quality and preservation.

    For seasoned numismatists, this stage is often one of the most rewarding parts of the auction experience.

  4. Step 4: Understand Auction Estimates, Reserves and Bid Increments

    Each lot is assigned an estimate, representing the expected price range based on rarity, condition and market demand.

    Some lots may also have a reserve price, which is the minimum price agreed upon between Downies and the seller.

    During the auction, bids increase in set increments determined by the auctioneer. These increments ensure the auction progresses efficiently while allowing fair competition between bidders.

  5. Step 5: Place Your Bid During the Auction

    When the auction begins, each lot is offered for bidding in sequence. Collectors may bid in several ways:

    • Live online bidding: Follow the auction in real time at auctions.downies.com using our Live Bidding Platform, or download our app from the App Store or Google Play. This service is free of charge.
    • In-room bidding: raising a paddle during the auction.
    • Phone bidding: with a Downies representative placing bids on your behalf.
    • Absentee bidding: where you leave a maximum bid before the auction begins.

    As bidding progresses, the auctioneer acknowledges each new offer. When no further bids are received, the hammer falls and the highest bidder secures the lot.

  6. Step 6: Winning the Auction Lot and Receiving Your Invoice

    If you are the successful bidder, the hammer price becomes the basis of your purchase. A buyer's premium is added to this amount, forming the total price payable.

    Shortly after the auction concludes, Downies issues an invoice outlining your winning lots and the final amount due.

    What is a buyer's premium?

    A buyer's premium is a standard auction fee added to the final hammer price of each lot. At Downies, a 22% buyer's premium (including GST) applies to all successful bids, with a minimum charge of $10 per lot, payable by all buyers.

    Example 1: If a trading card sells for $100, a 22% buyer's premium ($22) is added. The total payable would therefore be $122.

    Example 2: If a trading card sells for $28, a 22% buyer's premium ($6.16) would normally apply. However, because Downies has a minimum buyer's premium of $10 per lot, the premium charged would be $10. The total payable would therefore be $38.

  7. Step 7: Payment, Collection or Shipping of Auction Lots

    Once payment has been received, collectors may arrange to collect their purchases from Downies or have them securely shipped.

    Many buyers choose insured delivery, ensuring their new acquisitions arrive safely. Others prefer the pleasure of collecting their items in person, often taking the opportunity to explore our showroom at the same time.

How to Sell Collectables Through a Downies Auction (For Sellers)

For collectors wishing to sell important coins, banknotes, trading cards or other rarities, auctions can provide access to a global audience of knowledgeable buyers. Rare or desirable pieces often attract competitive bidding, helping achieve strong market results.

At Downies, consigning coins to auction is a carefully managed process. From initial evaluation through to final settlement, our specialists oversee every stage to ensure your material is presented to the market in the best possible way.

  1. Step 1: Contact Downies to Consign Your Collectables

    To consign with Downies, the journey begins with a conversation.

    Collectors interested in selling can contact Downies to discuss their coins or collection. Photographs and basic details often allow our specialists to provide an initial assessment of the material.

    Email us at auctions@downies.com or call us on +61 (03) 8677 8800.

  2. Step 2: Expert Evaluation of Your Collectables

    Once received, your items are examined by experienced numismatists. Factors such as rarity, condition and collector demand are considered to determine how the pieces should be presented in the auction.

    This evaluation helps identify the best strategy for achieving strong results.

    Coins example: As part of the consignment process, we'll grade coins using the Australian adjectival standard (VG, EF, aUNC, UNC, etc), however we don't slab the coins and give an official grade the way PCGS do.

  3. Step 3: Secure Consignment and Inventory Recording

    Every consignment is carefully documented upon arrival. Coins are receipted, catalogued and securely stored, ensuring complete transparency throughout the process.

    Security and accountability are central to our handling procedures.

  4. Step 4: Lotting and Auction Catalogue Preparation

    Next comes the transformation from collection to auction lots.

    Our specialists group coins into carefully structured lots designed to attract collector interest. Detailed catalogue descriptions are written, often supported by professional photography to showcase each piece.

  5. Step 5: Marketing the Auction to Collectors

    Once the catalogue is complete, the auction is promoted to collectors across Australia and internationally.

    Downies has built a global audience of numismatists over many decades. Through catalogues, email communications and collector networks, each auction is presented to a wide and engaged audience.

  6. Step 6: Auction Day and the Sale of Your Items

    When auction day arrives, your lots are offered to bidders one by one.

    Competitive bidding determines the final result. Once the hammer falls, the highest bid above the reserve becomes the sale price.

    For many consignors, this is the moment when the market truly reveals the value of their coins.

  7. Step 7: Settlement and Payment to Sellers

    After the auction concludes and buyers have completed payment, Downies finalises settlement with consignors.

    Funds from the sale are distributed according to the agreed terms, marking the successful conclusion of the auction process.
