About Stamps

  • How can I find out what mount size my stamp needs?

    There are two ways:

    1. On our website, the page of the stamp you need a mount for shows a box that says “Mounts – Click Here.” This section shows the recommended mount sizes for that stamp.
    2. Search for a specific mount size by typing the measurements into our website’s search bar.

    For example, if you need a 27 mm x 30 mm mount, type “27 x 30” into the search bar and click “View All.”

  • What are “space filler” stamps?

    Space filler stamps are stamps with serious flaws such as a crack, crease, gouge, or missing piece.  These flaws allow us to discount the stamps significantly. Many of these are older, in-demand stamps that you’ll want to own.  We call these “space fillers” because they allow you to fill gaps in your album at a significantly lower price. 

  • What is a minor-variety stamp?

    #C3a

    Some stamps have a “minor variety” of their normal stamp design. The Scott Catalogue states that these “…listings show a variety of the ‘normal,’ or major item. Examples include color variation or a different watermark…” Minor stamps can also include other random printing errors, including inverts and issues with perforations. One popular example of a minor variety stamp is #C3a, the Inverted Jenny.

  • Why was the mint stamp I ordered hinged?

    Mint stamps prior to the 1940s are more likely to have been hinged because stamp mounts had not been invented. After the 1940s, stamp mounts became more common, leading to less stamps being hinged.

  • How many of each stamp are issued with premium centering?

    The number of stamps with premium centering depended on how carefully the stamp was removed from the sheet or how precisely they were perforated. Due to this, the number of stamps with fine, very fine, or superb centering is unknown. See Mystic’s grading guidelines here.
