East Africa KM#24a [Risolto]

This coin, a cupro-nickel version of the otherwise bronze East Africa 10 cents of Edward VIII is a little peculiar. As far as I can work out, it was an error produced by the Kings Norton mint using the East Africa dies on a blank for the British West Africa penny. The existence of a mule with the East Africa obverse and British West Africa reverse points to the ease of confusion between these two coins. My concerns are two-fold. First, the image we have appears to be bronze, not cupro-nickel. Second, we have a rarity index of 66, implying quite a few member own this coin, which KM declines to put a price on (implying great rarity). Is there a way that we could invite owners to share an image of their coin to verify if it is indeed cupro-nickel?

I share some concerns, I suspect most (all?) of the 52 members who have added this coin to their collections have done so based on the photos, which were clearly bronze.

The member who added the images, diameter, weight etc., also had the composition changed from CuNi to Bronze. (because it's a bronze coin) And indeed it was you who asked for the composition to be reverted to CuNI.

I have removed the images for this item, as even the previous photos used were of a bronze coin:

This is a rare item, it way well be an unintentional off-metal strike, but information is too limited.

I think that's a good start. With any luck it will stimulate owners to check their coins. I'd forgotten I'd already seen this before. The weight must be wrong too. Assuming it was struck on BWA penny blanks, it would be ⅓ oz avdp. (9.45 grams). However, it might be best to delete the weight altogether until we have more information.

Do you want member names so you could message them?

Do you want member names so you could message them?

I guess that's something the referee should do?

I'm more inclined to believe member simply selected the wrong coin.

KM#24a was using images from a standard KM#24, a minority of members picked the wrong listing because it looked like the coin they had in their hands.

I think the best thing to do is simply move all members from:

1936 KN, N#34071

to the far more probable:

1936 KN, N#6229

If you want to send me the list of members, I'm happy to message them about the move, so any member lucky enough to own the Cupronickel version can re-select it, or even provide photos.

Just sent you the names. I will also move their collections now.

Thanks,

All members contacted…

interesting discussion

I have a 24a coin I believe

The coin on right is 24a-not in good condition, K of KN can be made out but a lot of corrison

Definately different metal type to the other 2 shown

Thanks for posting your images. I'm not sure I agree with your assessment that the coin on the right is a different metal. It looks to me like corroded bronze, not cupro-nickel. However, the real test is the weight. I appreciate that your coin is in a holder but, if you could weigh it, we could be sure. The bronze coins weigh 11.34 g, the cupro-nickel ones weigh 9.45 g.

I thought the same.  That's the one I would have picked as bronze for sure.  

Even if the poster does not have a scale, it is simple to devise a test to see if the coins are about the same mass.

Got hold of some jewelers digital scales and took coins out of pockets for you  and the 3 coins as per follows    11.15  g---------11.30g-------and   10.91g

Is that conclusive?

If we are right that the cupro-nickel errors were struck on BWA penny blanks, I'd say that it's clear this isn't a cupro-nickel coin.
