The application of Specimen stamps, world wide, have an interesting genesis. The meaning, in all cases, was a 'sample', an 'example', of a given issue.

Although the word has corrupted thru misuse in later, decimal issues from Australia Post, and indeed 'Stamp Fairs', Specimens were a necessary evil from the very beginning of any stamp production.

bulletChief among these needs was the UPU requirement for a 'specimen' of valid issues.
bulletIn general, not just Australia, "Specimens of stamps" were sent to UPU headquarters in Berne, Suisse, as part of the requirement of notifying them of authorised, valid for postage, issues. In most cases, these were sent in SHEETS of stamps, which were duly distributed as singles to member countries.
bulletOccasional use, in providing samples of a new color trial or some other instrument that required a 'specimen' sample of the result to be sent off the printing premises.
bulletTo members of parliaments eg,
bulletColor trials
bulletPresentation packs
bulletTo outside contractors preparing perforation machines,
bulletand etc.

The above were mostly covered by proofs, but fascinating handstamped specimens of the 1d red exist as trials of what was to come.

bulletPrinter 'specimen' sheets were common. A reference sheet to produce a given stamp denomination in the 'right' shade and color. In this case however, they were rarely overprinted or indicated as such.
bulletOffshore printers such as De La Rue would, naturally enough, keep 'specimens' as reference material. Perkins & Bacon Co regularly overprinted their trial printings as 'specimens' for the prospective customer.
bulletSpecimen packs for collectors

In all the above cases, 'specimens' as such merely had to be cancelled to prevent fraudulent use. Whether they were cancelled with a postmark, hand scrawled, hand stamped, or over printed, the result was that the written word 'specimen' came into general usage because that was, their specific, intended purpose. A specimen of valid postage for the UPU.  It also became the generally accepted term for specification requirements to outside contracts. "here is a specimen of the color we require"

And so, in order to provide collectors with cheaper material (which after all was pure profit at the end of the day for the Postmaster General), 'specimens' of current stamps, some cancelled to order (CTO), and some, printed 'specimen' were put together in post office presentation packs.

With the higher denomination stamps of 10/-, 1P & 2P, often rivalling any person's salary of the day, it was felt that these valuable issues needed a little more security measure than the risky wash-off-a-postmark variety. The GPO was concerned that they could, otherwise, easily pass as payment for telegraph and other, costly, bulk postage services, unless some clear indication of their NOT VALID status was apparent. Hence, in Australia, 'Specimen' overprints began.

*As a side note, the 'telegraph punctures' were instanced for the same reason, some method of clearly and permanently indicating that this valuable denomination, had been used. A simple postmark could not suffice.

 

Initially, handstamped specimen overprints were used. This, more than reasonably enough, was the modus operandi for all the colonial and state stamps sent to the UPU.  In hindsight it was not perhaps realised at the time, that there would be much more than a few sheets involved.

After the initial release of handstamped specimens, a more permanent arrangement occurred with a much later printed electrotype forme of 30 impressions.

 

 

 

 

 

Specimen stamps, (and their CTO cousins) were never popular. They were considered space fillers. In all, only around 10,000 'sets' or so were sold over a period of 30 years. (In contrast, over one million £2 Roos were issued) Being space fillers, many, quite probably, were discarded. For many years, they sold at a fraction of the 'real' price of their collected mint or used cousins. Not helping matters was that these packs lingered in the post offices. Available well into the 1940's. with no pressing  requirement to fill a void with a 10/- Roo (space filler that it may be).

Until the 'boom' of the 1980's, Specimen stamps remained as unwanted space fillers to the collecting public.

Thus, although the true printed quantities are now known, suggesting reasonable, not ample, quantities. There are two factors that make Specimens scarcer than may be thought:
bulletTheir space filler, discardable status. Many collectors still ignore them today.
bulletThe fact that some proportion of these specimen issues were sent to the UPU.
bulletThe status and value of these, are different to the 'collector packs'. They are unlikely to ever be separated and sold as non-UPU, standard specimens of any ilk.

Secondly, because of the general apathy associated with these packs, it took many years for the printing to dissipate. Thus some years transpired between printings.

Because of this, and not surprisingly, the next tranche of printings occurs (generally) on a newer watermark, and generally, with a new setting of the 30 on forme, with different type.

For this reason, the overprinted specimens can be separated into Type B, C & D electro type with the intervening years explaining the differences.

Overprinted Specimen

Electrotype formes of 30 made up as 5 stereos of 6.

 

The stamp sheet was divided up into four blocks of 30 prior to overprinting. All margins were removed to facilitate this. As such, There are NO imprints, monograms or other marginal markings for specimen overprints.

(Handstamped specimens are clearly, a different case).

Master Stereo Flaws:

A master stereo of 6 was used to create the others. As such, the same 'flaws' from the master repeat down the columns.

Damaged C1a variant

In the case of the type C overprint, the flaws are sufficiently prominent that all stamps in the 1st column show a damaged C. This is classed by specialists as type C1a. This flaw, repeating as often as it does, is therefore not particularly scarce, merely and interesting collectable type.

Block Flaws:

Since there were 60 stamps in left and right panes, repeating flaws peculiar to the block (rather than the master stereo) occur 4 times per stamp sheet.

Again, in the case of the Type C overprint, one flaw is prominent and classed as type C1. It occurs in positions 25 and (obviously) 55 of any pane.
