Australia KGV Official NSW Perfin 5d On 4½d

I have come across the attached mint stamp noted above, which I'm listing on Declampe and Hipstamp sites for a friend. The non-Official (eg no perf) SG number is SG130, but cannot see a SGO No in the SG Catalog, even without the NSW. Could someone please let me know something more about this stamp and a possible asking price

I think you need to think outside the box. This is a perfin and most likely was not issued this way. n The stamp was perforated with the initials by the office that used them. I suggest you try to find a perfin catalog for Australian stamps

Go to this website to get a nice PDF of Official Australia Perfins:

Having a look at my 2014 version of Stanley Gibbons, I think the stamp is SG 120 (rather than SG 130)??
I then checked the OS section of the catalogue, and like you, could find no appropriate number.
I then had a look at the same stamp in the Brusden White Catalogue for this stamp. It states that
"All punctured OS stamps are believed to be NSW State Government punctures."

This would indicate that these punctures occurred after the stamps left The Commonwealth Government Printer. Possibly the NSW Government may have requested a batch of punctures or they punctured them privately. Either way, they would be viewed as a state/private perfin. This would explain why they are not referenced in Gibbons.

Thanks for your replies.
I have contacted the editor of the Australian Perfin site one of you mentioned and he said it could be a forgery. BUT, considering it is mint and has the NSW perfin included, it looks like a very good forgery. Any more thoughts

It is interesting that he thought it was a forgery. Per another source of information ("A Collection of Australia 'Official' Perfins, Compiled by Roy Gault, June 2009), I see the following picture on page 15:

Nothing in ACSC says that it has to be used or mint, only that all known OS versions are OS / NSW.

As far as a value, I would price it the same as a Mint stamp of the same issue. Just my thoughts.

Brusden White catalogues recognise only Federal OS punctures.

The stamps punctured OS/NSW are not recognised as official stamps by ACSC. There is a statement in the Introduction page viii to the Kangaroo ACSC which is "Stamps punctured by State Government Departments for official use do not rank as Commonwealth issues, and we do not include these in this catalogue."

I believe this statement is also available in the KGV catalogues.

SG would also follow this as they have no way of independently valuing such issues.

I wish people would read their catalogues in full as it would help them to answer this type of question with a knowlegeable answer.

Maybe, it is not so strange. Perfins, mostly, come from stamp affixing devices that hold rolls of stamps that receive the perforated initials when the stamp is affixed. Contrary to an overprint, you would expect a perfin to have been used and at best have no gum.

The question then is whether these OS NSW perfins exist other than from affixing devices. If not, there is a good reason to think it is a forgery.
