A taxidermy armadillo, filed under Rocks, Minerals & Fossils

In the same online sale, an album holding thousands of postage stamps was filed under Postcards. Neither is careless: the category menu is long, the closing date is close, and the person choosing the category is usually also photographing, measuring and writing up the next lot.

Why it costs the house money

The category is where most buyers start. A taxidermy collector filters to taxidermy. A stamp collector filters to stamps. A lot filed somewhere else never reaches the people most likely to bid it up.

Fewer of the right bidders means a lower final price, and every fee in the sale is a percentage of that price.

The three findings from this screen

  1. 01CategoryA taxidermy armadillo, filed under Rocks, Minerals & Fossils.
  2. 02CategoryIn the same sale, a stamp album holding thousands of stamps, filed on a Postcards path.
  3. 03MarkIn another sale, an eyeglasses case with hand-painted lettering, plain in the photo and missing from the listing.

Each finding was checked against the lot's own photos and listing, then read again in a separate review before it counted. A mark too small or worn to read is reported as unreadable, never guessed.

The fix

None of this needs a specialist. It needs someone to look at every photo of every lot before the sale goes live, and to move two lots to the category their buyers actually filter by.
