This page is a census of known examples of the 1900 2½d brown-purple issue overprinted with the word 'SPECIMEN.' These handstamps are believed to have been for record or presentation purposes only and were not sold to collectors. They were not handstamped in this manner for distribution to the Universal Postal Union; mint stamps being used instead for this purpose.
A Scudder Specimen Type 9 overprint (Kenneth Scudder, Queensland Postage Stamps 1879 to 1912, p. 364) was used for this issue. It was typeset with sans-serif capitals, 15.5 mm long and 1.75 mm high plus a stop at the end. It was applied in red ink on mint gummed issues, wmk 2nd type "Crown Q", perforation 12.5, 13 in around 1901. One example in black ink is also known. At least one sheet was overprinted.
Examples are also known stamped SPECIMEN after receipt by various UPI countries and colonies, and Bechuanaland (on rosine (issued October 1898) and slate-lilac (issued January 1899) issues), Natal (on rosine and slate-lilac issues) and Tunisia (on rosine, slate-lilac and brown-purple issues overprinted in both violet and black ink) are shown below.
The Portuguese postal authorities in Lisbon stamped their examples ULTRAMAR in blue on the rosine issue issued in October 1898 and them provided them to postal authorities in their colonies and examples from the Goa postal archive are shown at the bottom of the page.
And finally I have also seen a specimen example on a turquoise-green colour trial for the proposed 2 shilling issue and shown at the very bottom of the page
