Poland - variants of circilation coinage 2010-2013

The main aim of opening this topic is proper preparation of some
requests to modify the coin catalog of Numista: 10groszy, 20groszy, 50 groszy and 1 zloty

https://en.numista.com/catalogue/pieces523.html

https://en.numista.com/catalogue/pieces521.html
https://en.numista.com/catalogue/pieces520.html

From 2010 till 2013 there are reported in the internet
coins of old type (as till 2009) and new type (as for example all coins from 2014-2016).
Some of them I have.
The easiest way to distinguish is "o" in "groszy" or "złoty"

for old type "o" has variable width (line thickness) of the "o" circle - as on the picture you can find using above links.
for the new type "o" it has constant line thickness
(Tomorrow I will send some scans - but the type of "o" is similar to
https://en.numista.com/catalogue/pieces102872.html).

On the other the same time there are reported some coins of wide rim (smaller diameter of stamp),
and some the double rim (additional circle) on obv., rev. or both sides.

At least least for old and new "o" I'd propose to create a new line in year (only while both types are confirmed)
and maybe leave current line for year with note like "undefined" variant/type.

Awaiting for your opinion and info about variants you have.

You make a good argument about details. Perhaps this topic is better suited for the "Numista coin catalog" forum where it may get the proper attention.

The scan of new obv type. (as an example)

​Harry,
Thank you for you advice, I thought about it.

Anyway I'll try to collect (I hope with the help of my Numista Colleagues) in this topic the whole information about requested changes (variants per year) and put on "Numista coin catalog" forum only the final request with all lines to be added.

I would like to help but unfortunately I don't have many Polish coins to contribute on the subject.

Hello,
i think it is a good idea, we could do as it was done here :

Please send me requests and i will validate.

Draft & some questions:

10 groszy: https://en.numista.com/catalogue/pieces523.

Revers1 - "o" in “groszy” has variable line thickness of the "o" circle
Revers2 - "o" in “groszy” has constant line thickness of the "o" circle

1990-2010 – Revers1
2011 – Revers 1 and Revers2
2012 – Revers 1 and Revers 2
2013-2016 – Revers 2
Are we going to leave 2011 and 2012 lines with the remark: ”Revers – not specified”?
And add two new lines for each year: 2011 and 2012? (Revers1 and Revers2)

What about 2011 wide rim (on Obv.). Are we going to add line per it?
(pictures to follow tomorrow)

There are also reported additional circles (close to the rim) on Obv and/or Rev
but I believe they should be considered as minting errors
and do not need additional line. (pictures also to follow tomorrow)

For 1999 I’d propose to add info that Varieties of mintmark placement are known

Dear Numista Colleagues.
-What is your opinion?
- Do you have/know any other variants of this coin?

PS. The coins listed above I have or are reported by Chałupski
