A price guide is a starting point. What similar copies are actually listed for right now is what buyers compare you to.
Values for popular titles move with movies, shows and speculation. A guide printed last year can be wrong this week. Recent comparable listings show where the market is today.
A graded 9.8 sells for far more than a similar copy in a sleeve. Mixing slab sales into your comps pushes the number up for the wrong reason.
One exact number gives false confidence. A low, middle and high range tells you where you can price a quick sale versus a patient one.
It builds a price range from current eBay listings, filters out graded slabs, and puts it on each row. For modern or reissued books, check the year and volume yourself, since older issues of the same title can be worth much more or less.
From current eBay listings for the same title and issue, with graded slab listings filtered out.
No. It is a guide built from comparable listings. Condition, demand and timing change what a book actually sells for.
Graded copies sell at different prices than ungraded ones, so including them distorts the range for a book in a sleeve.
