I read a book about Italian History. I saw a coin made in 1480 named "Lan Naissance de Venus r. BOTTICELLI"

I think there it is related to Monalisa & Leonardo Da Vinci.

it refers to the painting by Bottacelli the birth of Venus.
It has nothing to do with da Vinci or the Mona Lisa. This refers to the painting "The Birth of Venus" by Sandro Botticelli which now hangs in the Uffizi in Florence. I doubt, however, that your coin was dated 1480 as I believe the painting is dated to the period 1485-1486. Link to the painting below.
