British West Africa KM3 1/10 Penny 1911 H Diameter??? [solved]

Hi,

Just doing some research and have come across a size issue and was wondering if anyone has this coin and could measure it for me??

British West Africa KM3 1/10 Penny 1911 H

20.3mm or 20.5mm

Thanks

Jim

Could you please clarify if it is 1911 (KM#4) or KM#3?

So sorry about that KM4 is the coin that I am having a conflict on size, one source says 20.3 mm, another says 20.5.

Thanks

What are the two references to which you refer? I don't have a KM#4 but I have high grade examples of the KM#1 and KM#14 (Edward VII & Edward VIII 1/10 penny) and they both measure at 20.2mm. It would seem that the 20.5 may be too far out and it may be best if the Numista catalogue should be standardised at 20mm, similar to some of the other listings.

Hello, I measure my BWA1/10d 1911 and it is also 20,5 mm, btw. it is KM4...
Actually I measured a lot of(about 40 pcs.) 1/10d coins (random years) and they all measure between
20,1 and 20,4 roughly, it also depends on the condition of the coin, I guess.
And, please do not take this personal, but did you use the caliper on the right way?

Thanks radrick007 and Yvon,

Thought that was going to be the case. So we have verified that KM4 British West Africa is 20. 5 mm in size.

I ask, as I am designing coin albums (Dansco Types) and hole size is a major factor at this moment, still along way off from production but am slowly getting there.

Again thanks for your input and time.

Jim
