What does “packing slip” mean?

What it means

A packing slip is a manifest included inside a shipped package. It lists the specific contents, quantities, and sometimes unit prices of the items being sent. This is distinct from an invoice, which is a formal billing document demanding payment. For collectors and resellers, the packing slip serves as a secondary piece of provenance. It documents the item's journey from seller to buyer, providing context regarding its original packaging or transaction details. It is not the same as a receipt, which is a record of payment.

What it does to price

The presence of an original, legible packing slip can add a minor premium, typically 5% to 15% over a comparable item sold without documentation. This premium is most noticeable on items where provenance is key, such as rare books or vintage electronics. A slip detailing the original retail price can push the value up slightly if the item is known to be rare. Conversely, a slip that is heavily damaged, smudged, or clearly a modern reprint of an old document can detract value, sometimes resulting in a 2-5% discount due to uncertainty.

How to spot it

Packing slips vary widely by shipper and era. Look for company letterhead, order numbers, and item descriptions. Vintage slips may use specific paper stock or typeface common to the period of the item. Sellers should provide clear, high-resolution photos of the slip itself, not just the item it came with. A common mistake is confusing a packing slip with a shipping label; the slip details *what* is inside, while the label details *where* it is going. Fakes are rare but usually involve modern printing on aged paper stock.

Buying smart

Paying a significant premium solely for a packing slip is rarely justified unless the item itself is extremely high-value (e.g., a documented first edition manuscript). If the item is common, the cost of the slip is negligible compared to the risk of paying extra for weak documentation. A fair deal involves the slip being present, legible, and related to the item's known history. If the slip is merely a generic, unspecific document, the premium should be minimal.

Selling smart

Including a clear photograph of the original packing slip in the listing is a powerful tool. It moves the item from being "a vintage item" to "a documented vintage item." This documentation can justify a price increase of 10% or more, particularly when selling to serious collectors who prioritize history. The single most effective detail to photograph is the legible order number or date stamp on the slip, as this anchors the item in a specific transaction timeline.
