From which country is this coin?

Hey, it's a coin from Ethopia, https://en.numista.com/catalogue/pieces5947.html, the other too. https://en.numista.com/catalogue/pieces35722.html

If I'm correct.

Dit zijn de linksvan de munten, ik weet niet of ik 100 procent goed sit qua munt, maar zeker qua land.

Hi, it's from Ethiopia (king Haile Selassie I).

Regards, Tomas

how much are they worth ?

You can check it out here, http://www.ngccoin.com/poplookup/world-coin-price-guide.aspx . Fill in the country, year (if known) denomination. Not all years are the same, so that's the key, but i can't read ethopian.

 Ethiopian calendar / date converter; found at top of page in Numisdoc. Welcome to the site.  

P.S. I now also rotated your second image and used that converter, and both your coins are 1936 Ethiopia date, which is 1944 Western date.
