Except for Tattersall’s perfin “A” on cover, which are scarce, Tasmania’s private perfins on cover are rare. This is the first McKinlay’s Department Store perfin “McK/S/McK” on cover I have seen or heard about in more than 35 years collecting Tassie perfins. Cover is dated 22 February 1907. One image is of the stamp and the other is of the cover. The pattern suffered a progressive loss in pins from the original 74 in 1898 to only 64 at the end of its use in 1912. The image of the scanned hole pattern shows the state of the head February 1909 with 67 pins. The stamp image above shows that this perfin is missing the bottom row “McK” – only the top holes of the row show.

I just found a 2p dated 1904 with what looks to be 68 pins.
I am just starting to understand perfins, I have a few dozen with T, OS & A (lg and sm holes.)
Some of the T are very poorly aligned, on one the top is completely to the side of the vertical.
How scarce are McK perfins to begin with?
