Advisory Notes

The data model had been updated in the prior version 1.7 to incorporate vendor, certificate number and the images of a purchase invoice and certificate of authenticity for each stamp. Data files saved prior to version 1.7 will be automatically converted when opened.

It is currently not possible to view and import stamp images from your Photos app library. Open Photos and export an image when can be drag and dropped into the image area in Stamps.


The following are minor issues identified or ideas shared from our customers to be considered for inclusion in a future version of Stamps;

  • Ability to import stamp data (including images) and valuation from external site,
  • Add an estimated date of purchase checkbox when date is approximate or allow a blank date when it is unknown,
  • Add a duplicate checkbox (next to quantity purchased) to mark whether the stamp is a duplicate of a high value stamp (as opposed to common stamps using quantity greater than 1),
  • Add an estimated checkbox (next to purchased cost) to indicate the cost is estimated,
  • Ability to mark a stamp as a “wishlist” as well as a hyperlink to a valuation site,
  • Add the ability to record the location to show where a stamp is stored (e.g. stock pages, glassine envelopes, loose pages or albums),
  • Ability to add links to stamp images in a CSV file,
  • Ability to add category (or issue series) against each stamp,
  • Ability to add written notes for each stamp,
  • Ability to import a stamp image from Photos library,
  • Improvements to storing values for sheets (or ½ sheet) of stamps,
  • Auto-complete of text when entering data in fields,
  • Checkbox for whether the coin was sold out,
  • Checkbox for certificate being serialized, and
  • Addition fields for finish and edge type.
