Marking On Quebec Tercentenary Sc#101

I've never seen a marking like the one below on a Canadian stamp. Is it a number from a catalog I'm unfamiliar with, a grading system, an owner's mark or what? Any information would be appreciated.

Thanks in advance!

A plating number? It looks like pencil 48L01. Looks like a position dot upper left margin of the stamp.

I would agree it matches a possible plating format (position 48, plate 1 maybe?). It also could be an inventory number for a dealer (less likely imo).

Also could also be 1078h

Yes it could, which brings us back to Dan's original question.
On the face I see a dot in the 0 of 1908 and there seems to be something else in the center of the four words Canada Postage Ten Cents?Also a white accent above nt of Cents.

Just under inking..

Littleriverphil, it does look like a shark fin but it is part of the normal design. A great white lurking beneath the surface?

I do not know how many plates there were of this but it more than likley it appears as plate 48 position Left 01. Stamp flipped over and noted at bottom. The way the 4 is printed is more natural than how a h would be printed, and even so what would that normally refer to.

Addendum: With only 500,000 printed I now doubt it is plate 48. Maybe plate 4 8th row left position 1? Or is it possibly a dealer # . We will never know for certain.

Cert number? AIEP?

Except as regards the Postal Union denominations of 1c, 2c and 5c the
colors chosen for the stamps of this series do not correspond with those
of the regular set. The stamps were produced by the line-engraved
process, which has long been the standard method of production for
Canada's stamps, and as usual they were issued in sheets of one hundred
in ten rows of ten. It seems probable that the plates for the 2c, and
possibly for the 1c also, consisted of two panes of 100 stamps each
placed one above the other. This seems to be proved from the fact that,
whereas on most sheets the imprint "OTTAWA" followed by the plate
number, appears in the centre of the top margin, sheets of the 2c are
known with the imprint in the centre of the bottom margin, and in the
case of plates 3 and 4 both imprint and number are inverted. The
inversion on these particular plates was, probably, purely accidental.
But though these large plates were used the stamps were always issued in
the usual sheet size of 100. The following plates are known to have been
used:--

1/2c dark brown. No. 1.
1c blue-green, Nos. 1, 2, 3, 4.
2c carmine, Nos. 1, 2, 3, 4.
5c dark blue, Nos. 1, 2.
7c olive-green, No. 1.
10c dark violet, No. 1.
15c red-orange, No. 1.
20c yellow brown. No. 1.

Those are the plates used for this series. I have no idea why we say plate 48 for an 500.000 stamps printed!?

The series was printed on sheet of 100 , mean 10 by 10.

48L01 probably inventory no.

Wert, under inking? I am not sure.

My opinion is paper natural thing. I explain:

paper was wovw. Was wet and been full natural fibers, in some parts can react different during the printing,

You have very sharp eye to point this. I thing an microscope test will show clear what it is. If true under ink will be first variety in this denomination.

Interesting discussion! Let me throw out a hunch based on what I've read:

One plate was used. It was printed in two panes of 100 stamps each placed one above the other. So maybe it's an attempt at plating?

1078h = plate 1, stamp 078 out of 100 top pane (h) or:

48L01 = 48th stamp in the lower pane of plate 1

Keep the suggestions coming!

Thanks

danstamps54....The only reason I called it under inking is look at the colours taken from

1-White area of effected stamp.
2-Colour of white spot.
3-Colour of printed ink.

If it was a piece of paper stuck on the plate, the colour would be the colour of all unprinted areas...no ink would be applied, looks like dry ink print...See colour range below...Just an opinion as seen when I was a printer out of high school..

Robert,

I don't know anything about the inking of Canadian stamps. If it is the case that it was under inked, how does that relate to the notation on the reverse?

Dan

Hi Dan

These were steel engraving printing process.
Most plate numbers were 1-2-3 digits long.
Don't think it is a plate identification number..Just an opinion.

Below is a web page to contact Library and Archives Canada to ask a question....
http://www.bac-lac.gc.ca/eng/servic...uestion.aspx

I have a personal contact there and get information on files, sheets etc. but you can ask a question about possible plate numbering.

Use this information below when asking..
REFERENCE
Item Number: 1989 -565 . 000101 -001
Reproduction Number: POS-000155

I believe what you are looking at is some ones personal ID number for his/her collection..Again a opinion.


Robert

Robert,

Thank you for your assistance.
I gave it a shot and included the reference information you suggested.
I'll keep you posted!
Again, Thanks!
Dan

Robert,

I don't know if this is of any meaning or use, but I've already received a message (automated) regarding my inquiry.

It has a reference number: QMS-105235

Thanks again,
Dan
