Cook islands 2010 set corrections

Hi everybody,

I found some mistakes in the diameter of the next coins of Cook Islands:

- 1 cent
- 10 cents
- 20 cents
- 50 cents
- 1 dollar

can anyone check this information? I can't do it because I don't have any book with contains that data, but I have this coins in my collection, and the diameter is bigger in the five coins.

thanks
Regards

Details of 2010 Cook Islands coins ...

  1 cent            Bronze   3.6 g  17.1mm
  2 cent            Bronze   5.1 g  20.0mm
  5 cent            Bronze   6.2 g  22.0mm
10 cent  Copper-nickel  11.5 g  30.0mm
20 cent  Copper-nickel  14.0 g  33.0mm
50 cent  Copper-nickel  15.3 g  35.0mm
1 dollar          Bi-metal  11.0 g  26.0mm

Now I look at the page on here, if those above are correct, then these need changing ...

  1 cent   11.8mm to 17.1mm
10 cent   20.5mm to 30.0mm
20 cent  21.75mm to 33.0mm
50 cent  24.75mm to 35.0mm
1 dollar        blank to 26.0mm

honestly, I don't think they have 10 cents coins that are 30mm or even 50 cent with 35mm. those would be gigantic compared to coinage with same nominal value and these materials in the world around.

We don't need a book - we need those coins, a user and a ruler to check out the diameter.
I started to change the 1 one, because 11mm really sounded a bit too small.
the others however - it seems they're correct unless someone can prove the opposite

Hi Makake77,

I'm not telling lies, I only want to improve Numista with my first post here. I have these coins and they are really big, strange as it may seen, but true.

You can see all the set and compare the sizes in these ebay auction:

Obviously I can't put a ruler in that pictures, but at least you can see the "gigantic" size of the 10, 20 and 50 cents coins, and check that the sizes that appears now in Numista are wrong (I'm not a liar).

I hope that was enough    

Nice website by the way.

Regards from Spain!

noone's telling you a liar.     I just meant - judging diameters from images is rather difficult. and I had my
point. well - if that is so - I or someone else of the team will change the data.
please check yourself. you told you "have them into your collection".

I agree that 'we need those coins, a user and a ruler to check out the diameter'. I also used the photo in that second link, then reduced it's size a little to make the 10 cent image appear on my screen as 30mm like I suggested the actual coin would be. Then wrote beneath the photo all seven sizes as in my suggestion, then finally measured each on the screen and they match up with those sizes. I mention screen size as it depends on what size you have, whether you view the photo like I do; mine is 19" corner to corner.  Thanks :)

                                               

okydoky - changed all diameters mentioned

Many thanks to ZacUK and Makake77  

I realise that the size of 10, 20 and 50 cents are very big and sounds unusual, but Cook islands also have a triangular coin, so it seems they really like strange coins.

If I see some more mistakes that I can't change by myself, I'll write again in this forum, trying to do my best to prove the mistake.

I'm not a english native speaker, but I hope my english was understandable to you.

Regards!
