Medal???

good day please tell me about this medal, any information I am interested in the circulation and the material from which it will be made maybe an approximate value in Ukraine no one could help... 

r35mm / 16,83 gram

thank you

I couldn't find an exact match in the cataloge but there are a couple of medals with similar size/weight/obverse design:
N#239145
N#176634
N#284813
N#257866
N#356325

The composition is probably cupro-nickel, but to be sure, you can do a silver test on it: https://en.numista.com/forum/recherche.php?t=silver+test&n=&f=&s=&e=

I have no idea about the value, but considering that this is a souvenir medal, it's probably not so high. I've looked around on ebay and found some of the examples I've linked for sale, for around 10-15-20$. I guess that your medal is in that ballpark too.

This copy was in limited quantities as it was given to the guests of the event there were 3024 guests registered in total so I think not many of them survived
