The cancel is light, clear and well positioned. While not mandatory, a Circle Date Stamp is preferred with some collectors also preferring a light corner cancel leaving the design clear. F - Fine. The gum may be disturbed slightly due to heavy, multiple or improper hinging. The design has considerably less margin on one or two sides, but is clear of the perforations or the edges on imperforated issues.
Any clear postmark is acceptable.
VG - Very Good. Gum is disturbed or partially missing. Some fading of the colour is apparent. Defects such as creases or staining are present on the paper. The design touches the cut edge or perforation.
