Private perforation describes who applied a separating feature, not simply how an edge looks. If a collection requires material associated with a particular company or historical application, ask for that attribution explicitly. A perforated edge and a company-specific identification are different pieces of information. Understand the attribution in the term The National Postal Museum glossary […]
A wide unprinted margin does not, by itself, establish a gutter snipe. For a buyer seeking that specific configuration, the important questions are what material remains together and what supports the description of how it was cut. Confirm both before treating an unusual-looking margin as a named variety. Separate the space from the cutting claim […]
A stamp described as showing a doubled design is not yet identified as a double entry or a double impression. Those terms name different production events. Before buying for a specialist collection, ask which event the seller claims and what connects that claim to the actual offered item. Start with the production event named by […]
A familiar old stamp design on a souvenir sheet does not make the sheet part of the original issue. For an age-specific or issue-specific collection, identify the later sheet as an object in its own right and record the earlier design reference separately. A documented example of two different dates The National Postal Museum record […]
“Reprint,” “re-issue” and “the same design” should not be treated as interchangeable descriptions in a stamp inquiry. Before comparing offers, establish which historical event the seller is claiming and whether that event matches the object you want to collect. Use a named definition, not an assumed everyday meaning The National Postal Museum glossary distinguishes a […]
A historical stamp grill is a feature impressed into the paper, not simply a pattern that resembles dots in a photograph. If a grill classification determines your buying decision, ask the seller to identify the precise claim and its supporting evidence before treating a visually similar item as the required variety. Understand the term without […]
When an offer says certified, ask what the word refers to. It may describe a mail service, a delivery record or a separate expert opinion about a collectible. Clarifying that meaning comes before deciding whether the paperwork answers your purchasing question. A mail-service record answers a mailing question USPS describes Certified Mail as a service […]
Special handling and special delivery are historical service terms, not interchangeable descriptions of “faster mail.” For a collecting inquiry, identify the exact service category you need before asking for examples. Then decide whether a loose issue or evidence on a complete cover is required. Start with the historical definitions The National Postal Museum’s glossary describes […]
A postal-savings offer can contain several kinds of historical object: a loose savings stamp, a card bearing accumulated stamps, or a certificate recording a deposit. Specify which one your collection needs. A photograph of a monetary denomination does not establish that these objects are interchangeable. Three objects with different historical roles The National Postal Museum’s […]
A postal-note stamp is not simply an ordinary postage stamp with a different design. When reviewing a historical offer, first identify whether it contains a loose stamp, a stamp-bearing portion of a postal note, or other surviving components. Those objects support different collecting questions and should not share an imprecise “complete note” description. Start with […]
