A bag is bought on condition more than on anything else, and the condition of a bag is concentrated in a few places that photographs tend to miss.
Where the price actually lives
The corners. They wear first and they wear visibly. Show all of them.
The hardware. Plating loss, tarnish, a zip that catches, a clasp that no longer holds. Work the zip on camera.
The inside. Lining tears, pen marks, staining, loose threads at the seams. Turn it out and show it.
What comes with it. Dust bag, cards, strap, charm. Say what is there and what is not.
Shape. A bag that has been stored crushed may not come back. Show it standing as it is, not propped into a shape it does not hold.
Smell
Unglamorous and it matters. Storage smell, smoke and damp survive a parcel and arrive with the bag. If it has a smell, say so. A buyer who opens a parcel to an unexpected smell will return it, and will be right to.
On authentication
Buyers will ask, and the honest answer is what you can show: where you bought it, what came with it, any receipt, and any marks, stamps or codes the bag carries — shown on camera rather than described.
What nobody can do is settle authenticity over a video call. If you cannot establish a bag's history, say so and price accordingly. "Bought second-hand, sold as seen, I cannot confirm more than that" is a listing that sells and a sentence that protects you.
Delivery
Bags arrive crushed when they are posted empty and scuffed when they are posted loose. Packing bags.

Questions people ask
Should I clean a bag before selling?
A light surface clean, yes. Do not use anything that may strip or darken leather, and never try to recolour an edge before a sale.
Does a missing dust bag matter?
A little, and more on anything collected. Say it rather than letting the buyer notice.
Can I sell a bag I know is a copy?
Not as the brand, and not implying it. Selling a counterfeit as genuine is the clearest version of the thing the counterfeits policy exists for.
