Missing Color On 929

Has anyone seen this stamp before?

It is different from 929i. The background is wrong; missing a color.

The stamp is tagged GT2. Perforations are 12x12,5. The gum is undisturbed.

I bought it today. The dealer, told me that it comes a single sheet of 50, which was owned by K. Bileski.

I know the Bileski collection was huge and contained some great items. I don't have anything to see the regular but if MNH theres really no chance of changling from outside influences. I often wonder if the bileski named is used more than it should be to garner higher prices.

It's too bad that your dealer broke up the sheet of 50.

Kasimir Bileski had a massive collection and he was the first to discover (or announce) the discovery of the Seaway invert. It is because of the latter that I think your stamp might just be a changling because if it was in his collection then he would have announced it if it was anything other than just a changling.

The example of #929 is not a missing colour. The original colour of the background was magenta but, over the years, a number of these changed colours have appeared. The reason we say that the colour is not missing is that the background was printed in one colour only and one colour is present.

The stamp was shown in the Unitrade catalogue as "missing magenta" in the 2010 ( and prior) edition but was deleted in 2011. There is an explanation of this anomaly in the Unitrade catalogue.

I'm just wondering how during the print process the green
colour would be produced.

Here is the normal stamp Unitrade 929 on Abitibi paper






There was a second printing by AP on Clarke paper which
is virtually identical except perhaps a shade darker IMO.

Unitrade first mentions that the 6 value set was printed by Lithography in 4 colours and 929 light brown & multicolour.

Unitrade shows that 929i as missing magenta colour

As I'm sure most of us are aware in multicolour printing the combining of blue (cyan) and yellow produces green in it's
simplest form.

The normal stamp is in the red (magenta) range plus combining with black to produce grey and dark brown.

How would the green get there?

Either the wrong colour was added to a print run before it was discovered and this is printer's waste smuggled out or it's a changeling of sorts.

Unitrade 929i is now described as "brown background (colour shade)".

This is a correction to the 'missing magenta' listing from a couple of years ago. (time for a new Unitrade?)

As noted earlier in this thread, the background of this stamp, and all of the Artifact stamps, were printed by a single colour (not a mix of multiple colours).

The green colour variety is a fake, most likely due to some kind of chemical changeling.

Ask the dealer if he still has the "traffic light" copy...

The so called traffic light colours in the sheet margins were not yet included for the medium value definitives.

The were included on the low values of the AP Roland paper
printing of 1986.

An illustration of the green-coloured "pane" is shown in the July-August 2012 Corgi Times (bi-monthly journal of the Elizabethan II Study Group of BNAPS).

The left and right selvedge has been removed; a couple of large blocks and a couple of strips were illustrated (most likely these have been further split due to recent sales on ebay to unsuspecting collectors).

The Corgi Times article also states that a sheet of the green was part of the Bileski collection, and does not indicate that it is a "variety". It further mentions that another collector had included one in a display of fakes.

In October 2007 I visited the Library and Archives Canada in Ottawa and viewed the proof material for the 48c Cradle.

The printers described the colours as follows:

* pink (background)
* ochre (Canada 48)
* grey
* black

Each are "spot colours". That is, they are a single colour, not made up from the CMYK colour scheme. As such, you get a true single colour rather than a blend. As such, if one colour is missing, the affect would be very dramatic.

I have digitally re-created the colour separation to illustrate how this particular stamp was printed (all of the Artifact stamps were done the exact same way):

Thanks studystamps for that colour separation illustration.

The images show conclusively that most of these "missing colour"
examples are basically fake.

I didn't realize this material was public information! I think my next visit to Ottawa will have to include a trip to the Library and Archives!

Thanks for all the explanations guys, your are very knowledgeable and helpful.

I should have known better before spending money on this item

On the good side, I learned a few things and will be more careful in the futur........I'll try!

Re: Library and Archives

Philatelic material is available for viewing, but...

* the actual material is stored in Gatineau, QC and you view it in Ottawa, ON. As such, the material that you request must be moved a day or so before your visit. You must make a formal request for material prior to your visit.

* you must be "registered" with the Library and Archives (might not be the correct term - it has a decade since I did this, and it needs to be renewed every so often; it has been at least 3 years since I was there last). A phone call to their building would get you more details I'm sure.

* your request for material cannot be "I want to see whatever you have on Scott 929". Every item they have has been inventoried and catalogued. You need to use their file number when requesting. Again, I forget exactly how this is done. Somehow you can peruse their website and search their database to get the necessary information.

* some material has already been digitized and is viewable online, but not much of the proof material.

Moral of the story ... don't just show up on their doorstep and expect to see "stuff". It is not quite that 'easy'.

Do you have a link for that?

I think that whole procedure to view material is BS, I'm surprised
they don't make you jump a couple of hoops to see this stuff.

It's probably easier to get to see the PM, not that I want to see him.
