N. S. W. 1d Shield - The Types And Varieties Of The New South Wales One Penny Diamond Jubilee NSW

Indeed, Finches.

There is a hidden kaleidoscopic feast to be enjoyed under the UV lamp for these issues.

All of these stamps are die II - firstly under indoor white halogen room lighting then the same stamps under the UV lamp:

Fairdinkumstamps,

WOW !... A truly beautiful display of UV shades I'm seeing for the first time.

This was just a random selection from a pile of die II stamps - there are many more to be discovered!

Very attractive fairdinkumstamps!

The hoard I mentioned above predates the 1905 issue so it would appear that they'll not have the varieties you've shown.

BW doesn't mention any notable flaws in the 1902 printings, to which most if not all of my hoard belongs.

Bobby De La Rue,

There are constant flaws to be found on all printings beyond those listed by the ACSC.

Of the ones shown so far, the white flaw lower right of crown is on a stamp with SG watermark 65 Crown over NSW (type 3) from the 1902 printing and the three large white flaws can be found on the type 2 Crown over NSW issues (I also have it on Type 3).

The chances of finding a constant flaw among a few hundred are slim, but possible!

Thanks fairdinkumstamps, good information to know and have.

Fairdinkumstamps,

It's reported sourcing red pigment contributed to UV varieties on some 1d KGV stamps.

What circumstances, around 1898-approx', caused UV varieties on NSW 1d Red Shield shades ???

Finches, I don't recall seeing information about the ink recipes used at the time.

In Basset Hull's 1913 publication, the notes of the Committee of the Royal Philatelic Society (p.305) state:

The shades of the One Penny are somewhat difficult to describe - they are obviously aniline pigments varying in intensity and tone from a rose-carmine (sometimes almost approaching crimson) to a bright vermilion-scarlet.

Constant plate variety:

White flaws in shading left of right value circle.

Constant plate variety:

Large white flaw on top right ribbon.

Constant plate variety:

White flaws in left value circle and above right star.

A couple of other interesting varieties shown here, including a pair, one with variety, one without:

Jimjamtwo,
I have reposted your pair below with the crown pearl flaws and one with the secondary flaws highlighted.

There are varying degrees of degradation of the pearl flaws which warrant further investigation but not all have constant form and secondary flaws.

Your example IS a constant type as evidenced by the presence of secondary flaws including missing left end of the long horizontal scroll left of the crown, correct missing shading patterns and shape of the cross on top of the crown.

Thanks for letting me know, fairdinkum!

I have a stack of covers to go through, which may turn up other examples.

Jimjamtwo,
Here is another example of your constant plate variety:
