Coat of Arms

I think it would be cool if we could add a country's coat of arms to the page somehow, not sure how it would work but it would be a lot of work and maybe it is too much

I agree, Coat of Arms is frequently presented on the coins… 

What is more, I guess it could be worth to have flag, coat of arms, small map and 5-6 phrase of country description (geographical & historical info), no more to don't writenthe long text. Plus special section for coinage history (also short to not create too much text here).

If I correctly remeber, there was some country description in the history but it was closed.

yes that would be cool :)

Not sure too much information should be added…

But it would look nice to add the flag / coat of arms to the blurb at the top of the issuer page.

Yes, I think that looks perfect!
