Placing bids before the auction (pre-bid)

Absentee bids can be placed as soon as an auction opens, which is announced by email. Bids placed during this period are called pre-bids. If you are outbid, you will receive notification via email and/or within the app.

Bidding in a live auction

Before the auction, review the lot descriptions. If this is you first time bidding, please familiarise yourself with the lot descriptions and bidding increments. Please note that each lot is allocated 10 seconds bidding, with fair warning at five seconds.

We use the International grading scale for raw (ungraded/not encapsulated) coins; the Sheldon grading scale for third-party graded coins (see NGC and PCGS)
Reference: Fr-371; KM-674; Marsh-4; S-3785C
Reference works where the coin is described. This lot description includes: Friedberg (‘Gold Coins of the World’); Krause & Mishler (‘Standard Catalog of World Gold Coins’); Marsh (The Gold Sovereign); Spink (Coins of England and the United Kingdom). Note: for Australian sovereigns we use McDonald (‘The Pocket Guide to Australian Coins and Banknotes’) 
Mintage: 2,101,994.
The number of coins of a particular date struck at a given mint during a specific year
Diameter: 22.05 mm. 
Metric measurement
Weight: 7.9881 g.  
Metric weight
Composition: 916/1000 Gold 
916/1000 = 91.66% = 22 carat. Note: sovereign issues (including ½ sovereigns, £2 and £5) are struck in rose gold, the remaining 8.33% primarily a copper alloy. This is because gold is inherently a soft metal and using an alloy with a harder metal such as copper makes the coins more durable. 

Please refer to the glossary of coin terms for more information about the terms and reference works used in lot descriptions. 

Bid increments

Our auction system uses predetermined bidding increments and does not accept uneven bids. (For example, a £730 bid isn’t permitted, and would be rounded down to the nearest even increment, £725.) The bidding increments are as follows:

  • £1—20 bid step = £1
  • £20—50 bid step = £2
  • £50—200 bid step = £5
  • £200—500 bid step = £10
  • £500—1,000 bid step = £25
  • £1000—2,000 bid step = £50
  • £2,000—5,000 bid step = £100
  • £5,000—10,000 bid step = £250
  • £10,000—20,000 bid step = £500
  • £20,000—50,000 bid step = £1,000
  • £50,000—100,000 bid step = £2,500
  • £100,000 and up bid step = £5,000


Your bid activity and bid results will be available in real time, while finalised results will appear once the auction has ended. If any of your bids are successful, your invoice will be emailed after the auction.
