Question about the price guide
How are the prices determined? Is it just based on an average over x months? Is it a weighted average?
For example, if I had a book that sold as follows
6 months ago - 6 sales, $10 each
5 months ago - 1 sale - $5
4 months ago - 5 sales - $6
3 months ago - 1 sale - $15
2 months ago - 2 sales - $20
1 month ago - 4 sales - $25
The average price would be about $23. However, it looks like it started at about $10, dropped in price, and is now rising in price to about $25ish.
Can you divulge how you determine the overall value?

No rules are set in stone...
but for the most part I try to use the average of the last 5 to 10 auctions.
For some books, that's a 1-month average...
but for most, it falls somewhere between the 3-month and 6-month averages.
When only a few auctions have been seen, even after 6 months...
such as some of the rarer Acclaim books,
I try to use a conservative estimate until actual sales
prove that I should raise the value.
I'd rather say that a $50 book is only worth $20 "guide"
because there haven't been many sales
than to say that a $20 book is worth $50 "guide"
just because it sold for $50 the first time it showed up.
Case in point...
Shadowman Vol 3 #2 Variant DID sell for $399...
but it was the third individual auction for that book.
The first two sold for $20 average a few months ago...
so I feel better listing the current value of the book for $50
than I would if I made the current value reflect the $146 average.
I've tried to stop recording sales of books where the shipping cost
is higher than the book itself... since there's no way to know if the buyers
are combining lots of other books from the same seller to save on shipping.
(Such as buyers of NeatStuff auctions, or any books on Ebay under $2.)

Re: Question about the price guide
In your example, I would read the total averages for each timeframe...cjv wrote:How are the prices determined? Is it just based on an average over x months? Is it a weighted average?

So, I would see...
6 months average - $13.16, 19 sales
3 months average - $22.14, 7 sales
1 month average - $25.00, 4 sales
And I would probably price the book around $24 in the guide.

Re: Question about the price guide
Um how did you figure the "average" I think that you meant $13..cjv wrote:How are the prices determined? Is it just based on an average over x months? Is it a weighted average?

if you add up all of the sales you get 250 divided by 19 sales gives you $13.15 per sale. If you just add up what it was selling for each month you get $81 divided by 6 months gives you $13.50 per month...
lets see the median would be $10....
