EXTREMELY FINE GEM. THIS MAGNIFICENT USED EXAMPLE OF THE 1857 10-CENT PERFORATED TYPE I IS GRADED XF-SUPERB 95 BY P.S.E. -- THIS IS THE HIGHEST GRADE AWARDED.
Type I stamps only come from the 20 positions that comprise the bottom row of the plate. Due to narrow spacing on the plate and difficulties in aligning the perforating machine, stamps at the bottom of the plate usually have perforations cutting into the bottom portion of the design. This is a negative, because Type I is defined as having the design complete at bottom. The population of stamps showing the characteristic is extremely limited, especially when other factors such as soundness are taken into consideration.
Ex Merlin. With 2007 P.S.E. certificate (XF-Superb 95; SMQ $12,500.00). This is the highest grade awarded and only five others share it, a statistic that has not changed since 2013. This is also the first in this grade we have offered since 2012.
VERY FINE. ONE OF THE FEW COVERS KNOWN WITH A STRIP OF FOUR OF THE 1857 10-CENT TYPE I. FROM THE FAMOUS HARGOUS CORRESPONDENCE.
The strip of four pays the quadruple 10c rate to Mexico. We know of three Hargous covers with this size multiple.
VERY FINE. A RARE STRIP OF THREE OF THE 1857 10-CENT TYPE I ON A COVER TO AUSTRALIA.
The Type I stamps, with design complete at bottom, only come from the bottom row of the plate. This strip is scarce, and possibly unique used on a cover to Australia. It pays the 33c British Mail via Southampton rate to Australia.
