2 1/2 Euros World Heritage - Coimbra University, Proof issue

Coimbra University, founded in 1290, is the oldest in Portugal and among the oldest continuously operating universities in the world. Its inscription on the UNESCO World Heritage List came in 2013 — just one year before this issue — recognizing not only the medieval institution but the entire Alta and Sofia districts of the city that grew around it over seven centuries.

The 2½ Euro denomination was introduced by INCM specifically for collector-grade World Heritage issues, a format launched in 2010 that has no circulation equivalent.
