Golden Horde rosette [resuelto]

Dears,

someone can tell me about mont and year pls?

Coin is that one I think:

N#41947

Thanks for your time.

And please also about the follow one, that I think it's sane coin as before

Years aren't visible. On the first coin I think there is a part of "2" visible, so it shall be 752

Thank you!
