I have a catalogue of Euro coins that gives a description of all the designs. Here's what it says about the Portuguese 10, 20 and 50 Cents:
Castles and coats-of-arms of Portugal between the 12 stars - this design symbolises the dialogue, trade, shared values and dynamism that has contributed to the building of Europe. At the centre is the Portuguese royal seal of 1144. The coins were designed by Victor Manuel Fernandes dos Santos. Above two of the coats-of-arms can be found the initials of the designer (V.S.) and above another the initials of the Portuguese Mint (I.N.C.M.)
I personally find the main problem with Portuguese euro coins is that the dates are very hard to read with the naked eye!
