A recent eBay purchase arrived in my mailbox last week and I have started going through the stamps. It is another Nigeria lot which I posted about here. The stamps in the lot, with the exception of several pre-colonial stamps from Lagos, Southern Nigeria, etc..., were issued from about 1973 onward into the early 90s. It is definitely helping me fill some spaces and there are also a number of stamps from the definitive set referred to as Hides and Skins in the Scott Catalogue. Like the earlier animals definitives from the 60s, this is an issue with many varieties including two different printing methods, tons of color variation and a 1975-80 printing that is on watermarked paper. As many of you know, I use Steiner pages, and Steiner follows Scott. Steiner's pages also include the Scott minor number listings for this set. Below I have cropped just the listings for this series from my 2016 Scott Catalogue so you can see how it is listed. Scott makes an error here because they don't follow their own listing policy and it has led to a lot of confusion on my part. I circled in red, the printing method on the main set of stamps (at least according to Scott) that were issued starting in 1973. Except for the 50k denomination, all of these stamps were printed by the offset or lithography process, the 50k by photogravure. As you can imagine, my Machin identifying skills came in handy in separating out the various printings. But then we move onto the Scott listings for the minor varieties. Scott notes a printing of this set in exclusively photogravure, in 1973 and then goes on to list immediately below that a set printed from 1975 to 1980 on watermarked paper. Here is a photo of the watermark on one of the 5k Cattle Ranching stamps. It is the word Nigeria in a curve. In my photo you can see the last letter of the Nigeria in the center of the paper and the letter I and R to the right. The watermark is sometimes hard to see, especially if the design on the face is dark. So, as I mentioned above, the set from 1973 is listed as being exclusively photogravure which, again, you can see I circled in red. Scott notes at the front of the catalogue in the section that shows you how to read their listings that this header is called the "Basic Information on the stamp or set" and what is noted here holds true for all subsequent listings until a change is noted. Immediately below the 1973 set, noted as photogravure, is the watermarked set, not noted as anything except with Scott's watermark number. So, based on Scott's own description of how to understand the catalogue listings you would think these would be photogravure, right? NO. Imagine my confusion when every stamp I have ever identified from this set that has a watermark is printed by lithography. So with your help, now that I have the pages for Nigeria from the Michel catalogue I have been able to solve this mystery. With my handy-dandy, Michel German to English stamp terms glossary, I was able to read that the Michel catalogue notes all of the watermarked set from 1975 to 1980 as indeed having been printed by lithography rather than photogravure as Scott implies. So thank you all who were able to "lend" me your non-Scott catalogues. I can now go back and look at all my duplicate lithographed stamps, and may be able to find the remaining watermarked stamps from this set that I was missing.

The actual stamp described as Hides and Skins is the 1k denomination pictured in the Scott listing. In the eBay lot I received there were several examples of both the lithographed stamps and the photogravure stamps for this denomination. Here are examples of both including Sc. no. 291 (on the right) and Sc. nos. 291a and 291b (on the left and 291b is the bottom stamp). I have looked at all my 1ks for possible watermarks, which would be Sc.no.291c but I haven't found any. I am missing this stamp. On the other hand, having now examples of both 291a and 291b will fill spaces on that page so I am closer to having all examples of the photogravure varieties. The color variation is really noticeable on these stamps which is what makes this such an interesting series to collect. The below stamp confused me at first but I believe it is a quality control issue in the lithographic printing process. When you look at the numeral of value there is a fuzzy outline (it is actually a feature of the whole stamp). How would I more accurately describe something like this in philatelic terminology? Initially I thought I was looking at a photogravure stamp but the colors are similar to the lithograph stamp so I think it is more likely a messy lithographic printing job.

The 2k,Natural Gas, comes in all three flavors; lithographed, photogravure and lithographed with "NIGERIA" watermark. The Sc.nos. are 292, 292a and 292b and all can be seen here starting with the litho stamp at top left, photo stamp at top right and litho with wtmk on the bottom. I again looked at all the stamps of this set that I own...kinda looking for printing problems, possible flyspeck variations and the one thing that stands out is that there seems to be at least one stamp that is over-inked, if that is the right terminology for this problem. You can see it best on the bottom stamp. I have taken a close up photo of the designer/printer imprint at bottom right. It is barely legible. On the other hand the upper left stamp, cropped from the original scan of 3, has nice, crisp lines and has a clean, vivid color. So printing inconsistency is the name of the game with this series of stamps.

Here is a better example of how different the colors can be, just on Sc. no. 292.

Thanks daniel . I was aware of the Brixton Chrome blog already. I have that page bookmarked. Much of what he has on this blog, I believe is already incorporated into this page too Brixton Chrome. I doubt I will find anything new that is different from what he has already found but I am enjoying just looking at these stamps in detail and looking at the differences. The Brixton Chrome pages are to some degree what inspired me to start collecting modern Nigeria.

Great stuff; thanks for showing Darrin ( darkormex ) :-) I appreciate the study and analysis of the different printing methods. At the same time, let me through a spanner in the works and suggest that you consider the possibility of different papers as well. My own reference point is with the Portuguese Ceres issues. With these stamps, the different paper varieties used does have an impact on the appearance of the final product and in some instances is quite a stark contrast. Paper quality and some of the components which could affect ink absorption and the final appearance include: grain, brightness, surface, (coated or uncoated), thickness and even opacity can affect the results.
Just one more thing to consider...
Happy collecting!

stanley64, no monkey wrench at all. You are right. I sometimes feel like all I am doing is parroting back what the Scott Catalog states. I have definitely noticed paper differences so I will start incorporating this when I see them. I sometimes avoid this because I don't have any sources for paper differences for Nigeria or, except for the Scott Catalog, sources for paper differences at all. But I can certainly see them with my eyes and feel them with fingers.

All good Darrin ( darkormex ) :-) I was fortunate with the Portuguese Ceres to build and grow my reference collection of paper types from knowledge dealers here on the Iberian peninsula. The same is true for my current interest with paper & florescent varieties on Canada's Locomotive Series (1983-1986). Here too, knowledgeable dealers have been able to assist in the basis of a reference set.
For your own interests though and as you create that list, in addition to the look and feel do not forget the watermark tray or UV lamp. Where no list or reference material exists, you get to own and create one. I, for one, look forward to the list and updates; e.g. brilliant-white paper with no fluorescence, thick-smooth paper that is soft to the touch, etc.
Happy collecting!

Regarding those 1973 Nigeria issues:
A couple decades ago I took an interest in this series, and actually bought a FDC and a MNH set. According to the FDC, this series is called Decimal definitive stamps, Industrial progress and tourism. Most of my interest has been in covers with these stamps. I found this eBay lot to be interesting.
Note the reference on the printed sheet to Delacryl printing process for some of the values.
I had not heard of this before, an interesting online search subject.

JeffS, thank you for this reference. I am going to have to do more research. Since the weekend I haven't been able to spend too much time here or working on this. That FDC and others like it on eBay have been in my sights for a couple of months now. Some of them are pretty pricey. The name of this series you note above makes a lot more sense. I think, using the example of the 1k Hides and Skins stamp, is probably a wrong way of identifying this series. I noticed that the Brixton Chrome site just identifies these stamps by simply calling it the 1973-1986 definitive issue and I am going to re-title the thread as such.

This is Thomas De La Rue's brochure for the Delacryl process including a block of 6 dummy stamps. The link being that the Nigerian Security Printing and Minting Company was originally a joint venture with De La Rue. It must be disappointing for such wild variations in printing quality being produced by a security printer. On the other hand, from a collector's point of view it's probably more interesting Scan_20210518 by Daniel, on Flickr

When I look at the eBay listing that JeffS posted with the printing details for the various denominations, it notes that some denominations were printed photogravure and some delacryl. Catalogs list the two different types of printing as either photogravure or lithographed. Am I to understand then that Delacryl printing is a lithographic process, daniel?

Oops, I think I am able to answer my question here: deltastamps.com/Fact15LSD1967.htm. This website discusses the first stamps issued in the UK via this process and states, "By the late 1960's Special Issues stamps tended to be printed on the reel fed Thrissell or Woods presses, or sheet fed on the Rembrandt press. In 1969 the first Special Issues to be printed in offset litho were produced with the printing being carried out by De La Rue using their patented Delacryl process."

You can read more on the Delacryl process here, described as enhanced offset lithography. Daniel

Inspired by Darrin, darkormex , I purchased a few of these definitive stamps. Showing four examples of each of the 10k and 5k stamps. All clearly different.

I have to do a closer look into these stamps. I have a lot of the low values used and have noticed some difference on them, but not studied them closer.
I have also applied to the higer forces to extend the day from 24 to 30 hours.

in comparison with many of the above contributions, this one is going to seem tame, however, it has a little interest, I hope. Originally, this 3d. (S.G. 176 (The Cheetah), was issued together with another thirteen values in 1965/66 - the full range is SG 172 - 185, and printed photogravure by Harrison and apparently on chalk surface paper. The designer's name was Maurice Fievet and his name is included in the white frame at bottom right - all values from this '65/'66 printing omit Harrison's name. During 1969 -72, ten of these values/designs were re-issued - SG 220 to 230 - including the 3d., and this time printed by Nigerian Security Printing & Mining Co., Ltd., and their initials of N.S.P. & M. Co., Ltd. are shown at bottom left in the frame. There are other complexities affecting this set, plus what are some possible areas of re-touching, but the most obvious looks to be the digit 3 and lower case d., which appears narrower and more slender than later examples? The faint 'paw' on the bottom (later) stamp may be the result of soaking, but it does seem that quality of image appears sharper in the first printing from Harrison. This appears to be a reliable method of determining which of the two dates of issue you might have, by means of the presence, or otherwise, of a printers name. As always of course feel free to comment in whatever form:-)
