Bidding Information

As a postal auction, all our sales have a defined closing date and time (usually 24.00 hours on the closing day). All bids, by whichever method they are transmitted must be received prior to this cut off point.   We will entertain bid forms received after the close of sale but only in relation to lots which are unsold.

Please note that we do not levy any form of Buyer’s premium, lot handling fees or extra charges of whatever nature. We believe in complete transparency in the bidding process and are utterly opposed to specious revenue raising devices such as the aforementioned. We have no time for systems which can involve bidders paying up to 33% more in addition to their bid figures.

Entering a bid at auction forms a valid legal contract. We are happy to cancel bids if notification is received prior to the close of the auction, but after the conclusion of the sale, all bids must be honoured in full.

How Much Do I Bid?

The estimated price which we quote in relation each lot is the figure we consider to be the approximate market value of the item in question. We are often asked whether we consider items will sell at higher or lower levels than our estimates. There is really no definitive answer to that question. Thirteen years of trading have repeatedly proven the notion that auctions are a hugely inexact science. It is safe to say that with the aero-philatelic market currently being so buoyant, and with the demand for fine and clean material as strong as we can remember, the majority of lots will usually meet or exceed their estimated price. Bids entered at less than 80% of estimate stand little chance of success.

How Are Winning Bids Determined?

Our auction operates on the basis of the winning bid figure being calculated at one step over the level of the second highest bid (see Bidding Steps below). It is very important to note that this is not a tender situation where you automatically pay the full amount of your bid.  For example, if a lot is estimated at  £50.00 and we receive two bids of £60.00 and £70.00 respectively, the winning bidder will pay £62.00 (i.e. one bidding step above the level of the second highest bid). In the event of two identical bids being received, the first bid received shall prevail.

Types of Bids

The majority of bids we receive are of the traditional nature with an individual maximum bid figure listed in relation to each lot of interest. There are two exceptions to this general rule in the form of Limit Bids and Buy Bids which we also accept. They operate as follows:

Limit Bids – Clients often find that our sales contain a large amount of material of interest to them. However, their budgets may be limited to a certain figure. Rather than limit their bids to that figure alone with the possibility that they may spend far less than their available maximum they choose to operate our Limit Bid facility. Under this system bidders can list bids to a value well in excess of their financial limit with those bids being executed in preference order until their limit is reached by virtue of successful purchases. For example, a client may have a budget of £200.00 but may list bids to the value of £800.00 or whatever figure they choose.  As soon as their £200.00 limit is reached bidding ceases upon their behalf.

When adopting this method we request that clients list their bids in order of strict preference in order that maximum satisfaction can be guaranteed.

The fact that bids are subject to an overall spending limit must be clearly and unambiguously stated on the bid form. An overall limit cannot be calculated with postage & packing charges factored in as these are variable and unknown at the time lots are allocated. Any specified overall limit is by necessity exclusive of such postage & packing charges.

Buy Bids – This method of bidding is often misunderstood. It does not mean that a lot can be purchased prior to the auction at the estimated price. The confusion often arises because some companies operate a “Buy or Bid” model. Rather, a Buy Bid is an open ended commitment to purchase an item at one step over the second highest bid received – however expensive this may prove. For that reason it is a potentially dangerous method of bidding. If two bidders find a lot of special interest the Buy Bidder may end up paying far more than they anticipated. For example, if a lot is estimated at £20.00 and a bid is received of £80.00 as well as a Buy Bid, the client who entered the Buy Bid will be liable to pay £82.00 (one step over the second highest bid received). This scenario is not unknown – especially if we have underestimated a particular lot!

We do accept Buy Bids but we do not recommend them as we believe they are fraught with the potential for misunderstandings. We far prefer that bidders express an exact figure in relation to each lot of interest. If two Buy Bids are received, we will contact each bidder to establish a specific maximum figure in order to resolve the deadlock.
