Hong Kong 10 cents 1959 without mintmark [επιλυμένο]

I've got the above coin, but looking at the Numista page for it (https://en.numista.com/catalogue/pieces1574.html), it only lists the year 1959 with an H mintmark. Is there a line missing on the catalog page, or am I just not seeing the H?

I have a 1956 H as well, where the H is clearly visible where it should be.

(You'll have to excuse the picture quality, they're taken on my mobile phone through an overlaying LED magnifier - the only way I have to take close up shots).

ΑπόσπασμαOur ten-cent coin has no mintmark. This means it might have been minted either in the Royal Mint in London, in the Hong Kong branch mint or at James Watt & Co. Soho, Birmingham.​

​just found, maybe helps.

Thanks for that! Looks like there should be a line more on the catalog page then, for 1959 with no mintmark.

I have one 1959 without mintmark as well.

Απόσπασμα: "ngdawa"​I have one 1959 without mintmark as well.

​Cheers - apparently there should be another line on the catalog page. The NGC price guide only lists a 1959H though.

I can't add a 1959 no mintmark line on the catalog page, and as far as I can see there is no referee for Hong Kong. Who do I ask to add the line?

After closer inspection, I think I see an H mintmark on the above coin at the second possible location for it - below the N in CENTS. I did look for that on my coin without any luck, is it possible that it has just faded away? Perhaps this is also the case with yours, ngdawa?

​You are correct (sorry but no prize).
The "H" mintmark of 10-cent 1959 coin is located below "N" of "CENTS"

So there are two different locations for the mintmark? I'll check mine then!

For the 1956 the H is after CENTS, but for the 1959 it is below the N in CENTS. I still can't see the H anywhere on my 1959 coin, but I guess is has just faded away through the years.

​I guess the same has happened to mine. When I know it is there I believe I can see it, but I am far from sure.

This is how it looks like:


And if I really concentrate I believe I might perhaps see an H about here:

If there was once an H on my coin, it is definitely almost entirely faded away by now as well.



Anyway, I've labelled it as a 1959 H and will mark this topic as solved. Thanks for the replies, guys :-)
