Guidance Notes

We offer the following guidance to give you an indication of how we do business. Our aim in all this is to ensure that we give you the best service we possibly can and that you are satisfied with that service. Our Satisfaction Guarantee is spelt out at the end of this section. Please read these notes in conjunction with the Terms and Conditions of Business on the JACDA website and inside the back cover of the auction catalogues.

How the bidding works

All bids may be made through the website or by e-mail. We regret that we are not able to accept telephone or fax bids. No bids will be accepted after noon UK (local) time on the closure day posted on the website and printed on the front cover of the sale catalogue. We emphasise that this is not an online auction. The website is merely a different method of delivering the catalogue and submitting bids – real-time electronic bidding is not possible.


“What you bid is what you pay”. If your bid succeeds, it will succeed at the value you enter on the bidding form. There is no connection between the winning bid and any others that are made. If only one bid is received at or above the reserve price the hammer price will be that bid.

Upset price, reserves and estimates

The upset price for JACDA is £10; i.e. there will be no lots valued below £10 entered into the auction and no bids below £10 will be accepted. Reserves will be as agreed between the vendor and JACDA. Not all lots will carry a reserve. Estimates are our opinion of the price range within which the lot will sell. Estimates are not predictions of selling prices. There is no fixed linkage between reserves and estimates.

Bids below estimate 

We welcome such bids; we respect your opinion. We only ask that you signify a below-estimate bid by placing brackets around your bid as we might need to contact the vendor.


If you wish, you can give me discretion to increase your bid by a given percentage. If your original bid succeeds, that is the price you will pay. However, if you are outbid, discretion allows me to increase your bid accordingly.


Commission for both vendors and buyers is 20% of the hammer price.


We accept payment by electronic money transfer (sterling transfers are free. My bank’s fee for cross-currency transfers is a £7 flat rate). By PayPal (who charge 5% fees);  We do not accept payment by credit or debit card. I expect payment to be made in full within 14 days of receiving the invoice. If this is problematic, just mail me.

Prices realised 

We aim to display these on the JACDA website within 7 days of closure.

Post and packing charges

Post, courier, packing and other packaging and delivery charges will be billed at cost. Overseas buyers have the option of despatch by air mail or surface mail.


Insurance of purchases in transit is at the discretion of the purchaser. If the purchaser gives no instructions that the item(s) should be insured, JACDA shall not be in any way liable for any damage to or loss of or destruction of the item(s) whatsoever and however caused. Vendor’s items will be insured at the vendor’s expense whilst on JACDA premises. The rate for storage insurance cover will be £1 per £100, subject to a minimum charge of £1. Further details are given in the Terms & Conditions


Reserves are a private matter between the sellers and ourselves. Please do not ask us to breach this trust.

Satisfaction Guarantee 

We shall treat all reasonable complaints with care, speed and consideration. The buyer should inform us of his or her concerns within seven days of receipt of any lot which in his or her view significantly fails to conform to our catalogue description. The way in which the item fails to match the description must be made clear. The buyer will bear the return postage costs in the first instance. If the complaint is upheld, the sale will be set aside and the hammer price, commission and return postage costs will be refunded in full.
