So I found my grandpa's medal, no one in family knows where it came from. Can someone help identify it?

So you don't have to squint your eyes to read the text, I'll include it here alongside my attempts on the translation. The orginal language is Polish.

(The marks are in left, top corner) O side, from left to right, from outer to inner circle. Clockwise.

"Twoja osobowość jest prawdziwa" (I translated it to: Your personality is real) Note: 11 stars on the bottom.)

"Jednośc Służba Zdrowie" (Unity Duty Health)

X side, from top to bottom.

"Boże użycz mi pogody ducha abym godził się z tym, czego nie moge zmienić" (God lend me serenity so I can reconcile with what I can't change) Note: In polish this sounds more pleading than how I translated it.

"A * IX * A"

"Odwagi, abym zmieniał to co mogę zmienić" (Courage, so I can change what I can change)

"I mądrości, abym odróżniał jedno od drugiego" (Wisdom, so I can distinguish between one and another)

This looks like an Alcoholics Anonymous chip denoting the years in recovery. In English they usually say "To thine Own Self Be True" and "Unity Service Recovery".

Hopefully that's a useful starting point for you.
