2004 Large Head 20c Pieces

There sure are lot of errors on the small head design, perhaps that's why they abandoned the technology. To date I have found many from searching circulating coins.
Here's some of what I've found so far, but is by no means completed yet.

Has partially filled die on the 2 and 0 reverse. Shows on the the top and bottom of 2 and both sides and top of 0.

Has quite a large fill on the back of the platypus head and water line. Also on the top of the loop on the 2 reverse.

Very weakly struck hairlines obv.

Has very strong letter doubling AUSTralia

Has Cud under chin and base of neck as well as letter doubling obv.

Has Cuds under chin, neck, along the top of queens hair, and good letter doubling obv.

Has strong double lettering obverse and nice dc from low austALIA going up through top of last A to the rim.

Has doubling to most of the lettering obverse and base of the queens neck
Has a good Cud at the back of the queens head.

Has many little dotted Cuds around inside of rim on the right side obverse.

Just inside rim Has dots/cuds most of obverse.

Strong doubling to queens nose..

Has a small Cud on top of queens hair and doubled platty mouth.

Has Cud top and back of queens hair.

Has doubling chin, neck, hair and platypus mouth.

HAS LARGE BLOB on top of the 2 reverse.

Has 4 little Dots/dashes above SD reverse.

Very weak hairlines and back half of queens crown obverse.

Mind you, a lot of these are also found on 2001 and later traditional design 20 cents also.

Guess who's found another one? me!! 6 now... :)

Before ppl ask, this is the SAME coin! The difference in finish on either side is extraordinary; its like the Obverse is the current Cupro-Nickel finish, while the Reverse looks and feels like the finish on a 1970's 20c. As for the Obverse, massive numbers of what seem to be Cuds or delaminations (or both), as you can well see.

Looks like it was found on the ground at once stage.
Only my opinion.

I don't know what to say, part of the Obv appears to have peeled and the rev looks like its going rusty as though it's got steel in it? Beats me.

Nancyc: exactly. The Obv seems to be plated with Cu/Ni or something (has a similiar finish to every other 2004 Ive seen) onto some sort of core; the material around the area's that are 'peeling' is VERY loose - and SHARP!! You can notice that the 'shinny layer' peeling away is NOT taking the impression with it and leaving a smooth surface (which suggests to me it is in fact some manner of plating and not just 'layers' of metal created during the rolling process, which would leave a much rougher surface that would not retain as much of the impression).

The Rev is TOTALLY different, with a degree of CORROSION!

All I can think of is, the material used for the plachet was contaminated at some stage. Also, ARE the modern Cu/Ni coins plated in some way? NEW coins these days seem to have a much more 'shinny', mirror-like lustre when UNC.

Either way, its a rather unique looking 20c!

Well Ben,
We will know Sunday night what you might think they are worth!

cheers
