Need help identifying Vietnamese object [Resolvido]

When I got it from my grandfather, he told me it was awarded for bravery sometime in the Vietnam War or the August Revolution. Can anyone find out about it’s origin and value?

 Quote:  On the medal, "DOC LAP TU DO," translates to "Independence and Freedom" and 

is a quote from Ho Chi Minh, "KHONG CO GI QUI HON DOC LAP TU DO" 

(Nothing is more precious than independence and freedom), 

featured on a circular gilt medal with Ho's profile. 

 It came with a top part and pin >
