They are remainders CD, this is directly from the PISC website:
Quote:
Used examples of the 1882 5/- issue are, more often than not, found with a "remainder" cancellation. This is because, in about 1906, the remaining stock of 264 sheets (13,200 stamps), along with other values still on hand, were cancelled and sold to a stamp dealer. The most commonly found date for these cancellations is 15 DEC 00, but others exist. An unused example of the issued stamp, which was lithographed and perforated 10, is illustrated on the left, above.
Among the 5/- remainders was an unknown quantity of stamps with an electrotyped frame which had never been issued for postal use. These stamps are decidedly scarce, and an example is illustrated above, on the right. The colours of the electrotyped variety are pale compared with the issued stamp and the perforations may differ - the example above is perf 11.8. There are other differences in the electrotyped version: the circular frame line around the Queen's head appears thicker and the star at lower left touches the frame near to the F of Five.
It should be noted that, also among the remainders of the lithographed 5/- stamp, there was a quantity of imperforate examples, often with badly misplaced centres.
