A variety of the 3d denomination is catalogued with "double transfer".
This is, of course, a plate variety caused like all similar ones by a
faulty or incorrect rocking of the roller impression on the plate and a
correction on top of this impression which did not always entirely
obliterate the first impression. Mr. Howes says this variety "is
recognized by the letters EE PEN being 'doubled' at the top, making it
appear as if a line had been drawn through the words and giving it the
name occasionally used of the 'line through threepence' variety." There
are at least two other similar varieties of "double transfers" known on
this value for in the _Philatelic World_ for December, 1908, Mr. A. J.
Sefi described and illustrated three different ones. One of these is a
variety mentioned by Mr. Howes, another shows a distinct doubling of
parts of the details of the two left-hand corners, while the third
variety shows a doubling of the upper right hand corner. It is quite
possible a close study of these stamps would reveal others and also
similar varieties in the 6d and 12d. "Double strikes" are not uncommon
on stamps produced by the line-engraved process though they are not
often so striking as the first of these Canadian varieties and those
found on the United States 10c stamp of 1847.

According to a valuable summary from official records published in the
_Metropolitan Philatelist_ we learn that the first delivery of stamps
from the manufacturers took place on April 5th, 1851, when 100,000 of
the 3d denomination were delivered to the Canadian Government. On April
20th, a second supply of the same value comprising 150,200 stamps
arrived in Canada. On May 2nd 100,400 of the 6d were received followed
two days later by 51,400 of the 12d this latter being the only
consignment of the highest value ever received from the printers. We
have already pointed out that the 3d was placed on sale on April 23rd,
1851. The date of issue of the 6d is not known for certain as there are
no official records relating to this though, as a supply was received on
May 2nd, they were doubtless issued some time during the same month. The
12d was issued on June 14th as we shall show later.

The three values of this series, as well as other denominations in pence
issued later, were withdrawn from use on July 1st, 1859, when decimal
currency was introduced. By means of much diligent search through Post
Office Reports and other r
