New Guinea, 1 penny, 1936.  Obverse.




New Guinea, 1 penny, 1936.  Reverse.


My next exhibit is from the Territory of New Guinea. It was administered by Australia at the time.

The dentillations, if they can be called that, are a combination of semi-spheres and the most disgustingly, disgracefully sharp and spiky dentillations in the whole history of numismatics. It makes me wonder what artist George Kruger-Gray's mental state was when he thought of using such shapes.

New Guinea, 3 pence, 1935.  Obverse.





New Guinea, 3 pence, 1935.  Reverse.


The New Guinea three pence coin was similar, as was the sixpence (not shown).

That's an intriguing idea. I have never read the files in the National Archives (London) relating to New Guinea, so I cannot say. However, given the highly unusual nature of these semi-beads and denticles, there might indeed have been an unusual reason for them, so who knows?

Uruguay 10 pesos 2000.jpg

Uruguay, 10 pesos, 2000.


Here the dentillations do not reach the rim.

Are they marking time, as on a clock?

There are exactly 60 marks on the ring...

An unidentified coin is a piece of metal. An identified coin is a piece of history.

Oh, thank you, Herr Asperger! You counted them all.  :-\

Mali - coins of 1975 to 1977.


Here you have four triangular shapes around the denomination.

They appear to point to the similarly triangular shapes around the rim.

Barbados $1 1973--.jpg

Barbados, 1 dollar - circulation coin.


This heptagonal coin has a bead circle on both sides.

Admittedly, all the other coins in the series also do, but they are all round.

Two, rather than four is the magic number. The four inside triangles are sometimes solid, like those on the rim, sometimes divided in three plus the outline is four triangles and there are four of each. However, there are 32 triangles on the rim of each coin (I counted them just so you could call me an asparagus) and 32 is a power of 2, but not a power of four.

I would never call you an asparagus - you could get eaten alive by literal-minded vegans. Asperger's, perhaps.  ;)

32 certainly does not fit within a decimal system, so you can see why the Malian franc did not survive for long after that.  :-X

The Cyprus coin series of 1955, with QEII on the obverse, had denticles on both sides.

In 1963, after independence, a new series was issued. This set had denticles on the obverse but an unusual wavy pattern on the reverse.





Cyprus, 50 mils, 1981.


Why wavy? Cyprus is an island, so is the pattern meant to represent the sea?





Cyprus, 5 mils, 1963.
