The estimates indicate what you can expect to pay for a stamp that is in Very Fine condition, without faults. How to Collect Lets imagine you were collecting airplane stamps - stamps featuring illustrations of airplanes. You would then receive a list of stamps with the Scott catalog numbers referencing these items. Now, all you do is look it up in your nifty 6-volume edition of the Scott Catalog and decide if that is a stamp you would like to see in your collection. Grade addresses only centering and cancellations.
Condition refers to the factors other than the grade.
Condition Refers to factors other than the grade that affect the value. Imperforate stamps may have small margins, and earlier issues may show the design touching one edge of the stamp design. For perforated stamps, perfs may barely clear the design on one side, and very early issues normally will have the perforations slightly cutting into the design. Used stamps may have heavier than usual cancellations. Imperforate stamps will have tow margins of at least normal size, and the design will not touch any edge.
