They are unique pieces due to their limited print run, exceptional treatment and aesthetic value.
They are overlay-printed using the same printing process as certain stamps. This allows for the engraver to verify the accuracy of the engraving and, when it is considered of high quality, a reduced print run is carried out, something that is highly valued as a stamp variation by philatelic collectors.
In the last few years, they have been made more exclusive by adding gold, silver, bronze, ceramic, etc., in the reproduction of the stamp motif.
