Sales statistics after 18,000 sales

14 Jun 2009

As promised, here are the statistics after 18,011 recorded sales from online auctions.

The sales have resulted from 33,625 auctions started, so the success ratio (i.e., auctions resulting in a sale) is 53.56%, now having stabilised at this level (and in fact increased slightly). The number of successful auctions per month has continued dropping, and is now just about 305 from about 310 last time. I think I need to have another look at non-eBay sites - another job for this summer.

There are 1049 different editions and variants listed separately at BDKR.com Of those 950 (947 after 17,000 sales) have appeared in at least one successful sale, and of those, 82 (85) have appeared once only.

Generalgouvernement remains the most sold edition with 144 sales (last time 137). Among the English-language editions, Great Britain 7 (1910) is now the most sold at 137 sales, while the best-selling French edition is as before Sud-Est de la France 9 (1910) on 70 sales. Of the 18,011 books, 7878 (43.7%) were in German, 7618 (42.3%) in English and 2515 (14.0%) in French - pretty much unchanged proportions. So it remains a steady rule of thumb that, out of seven sold books, three are in German, three in English and one in French.

The total sale price for the books was €622,114.55, giving an average price of €34.54, continuing a very slowly falling trend. If all the books had gone for their BDKR guideline price, the total sales would have been €1,502,825, so the ratio is continuing to edge down to 41.4% from the previous 41.8%. But this may just be because we haven't had any major sales recently.

The average number of bids per sold book stays at 5.3. As ever, just treat these stats as a bit of fun - nothing to take too seriously. They also appear in shortened form every day on the stats page. If you'd like some other data, please feel free to ask!
