| Stamp Set | The revaluing was done by means of a hand numbering machine set to repeat and was executed with surprising accuracy.
Due to the nature of the overprinting errors and varieties are found. The most prominent and also very rare error is the “Double Value” error. Varieties such as broken figures and light or weary impression are more common.
The overprinting was done by the Postmaster, HP Wynn, himself. |
