A stamp can commemorate a charitable purpose without your present purchase generating a new donation. Before accepting a seller’s statement that a purchase “supports” a cause, ask whether it describes the original issue or makes a promise about this particular transaction.
The American Philatelic Society vocabulary explains semi-postals as issues sold above their postage value, with the difference supporting a cause or charity. That explains the issue category. It does not establish how a later resale payment will be handled.
Separate the issue description from the transaction promise
Keep two fields in your buying record. The first identifies the issue and the source describing its original purpose. The second records any contribution expressly promised as part of the current offer. A historical description belongs in the first field even when the seller places it next to a purchase button.
If the offer only describes the original issue, do not add your own claim that buying it now funds the same organization. Conversely, a seller may make a separate current contribution promise. Review that promise on its own terms rather than assuming the stamp design explains it.
Ask what will happen to this payment
When a current contribution is advertised, request a written answer to these transaction-specific questions:
- Which named organization or cause will receive it?
- What amount or calculation applies to the item and quantity being quoted?
- What event triggers the contribution, and when is it to be made?
- Which offer terms describe exclusions, cancellations or other conditions?
- What supporting record will identify the promised contribution without exposing unrelated customer information?
A percentage alone is incomplete if the calculation base is missing. For example, “a portion of proceeds” does not explain whether shipping, taxes or other amounts are included. Ask the seller to specify the base; do not choose one on their behalf.
Compare two hypothetical descriptions
Consider a fictional listing that says, “This issue originally raised funds for a named cause.” It supplies historical context but says nothing about a new contribution from the resale. Your record should say “original issue purpose described; current contribution not stated.”
A second fictional listing says, “Part of this sale goes to charity,” but does not identify the beneficiary or calculation. That is a current claim with missing terms. Keep it unresolved until the seller supplies the relevant details. Missing evidence is a reason to clarify the offer, not proof of misconduct.
Do not calculate a donation from the asking price
The resale price and a printed denomination are different fields. Subtracting one from the other does not establish a donation, a seller’s margin or an original surcharge. Preserve any quoted contribution separately from the item price and shipping scope. The guide to denomination and asking price explains that monetary distinction.
Likewise, a current contribution statement does not establish the item’s identity, authenticity, availability or postage eligibility. Those remain separate questions. This review also does not determine tax deductibility or authorize a fundraising claim.
Send a request tied to the actual offer
If an inquiry starts from our PDD-013 catalog reference, include its URL and identify the actual item you want reviewed. The catalog reference is not a statement that semi-postal stock or a donation arrangement is available.
Use the contact page to ask: “Does the quoted transaction include a current charitable contribution, or is the wording only describing the original issue? If a contribution is included, please identify its beneficiary, calculation and applicable terms.” Keep the answer with the quote before repeating a benefit claim to your own customers.
