Meaning |
| Chalky paper |
A chalk-surfaced paper for
printing stamps. Any attempt to remove the cancel on a used
chalky-paper stamp will also remove the design. Immersion of
such stamps in water will cause the design to lift off. Touching
chalky paper with silver will leave a discernible, pencil-like
mark and is a means of distinguishing chalky paper. |
| Changeling |
A stamp whose color has been
changed-intentionally or unintentionally-by contact with a
chemical or exposure to light. |
| Charity seals |
Stamp like labels that are
distributed by a charity. They have no postal validity, although
they are often affixed to envelopes. United States Christmas
seals are one example. |
| Charity stamp |
See Semipostal. A stamp sold
at a price greater than postal value, with the additional charge
dedicated for a special purpose. Usually recognized by the
presence of two (often different) values, separated by a
"+'' sign, on a single stamp. |
| Cinderella |
A stamp like label that is
not a postage stamp. Cinderellas include seals and bogus issues,
as well as revenue stamps, local post issues and other similar
items. |
| Cinderella stamp |
Virtually anything
resembling a postage stamp, but not issued for postal purposes
by a government postal administration and therefore usually
omitted from the standard catalogues.
