#1 - 50 millemes from Libya, dated 1965 AD # 2 - 1 drachma from Greece #3 - 20 stotinki from Bulgaria
From the second series: #1 - 5 millim, Tunisia #2 - 5 millemes, Egypt, dated 1960 #3 - 20 millemes, Libya, 1965 #4 - 100 millimes, Tunisia They don't have any value other than street value in country of origin, so yes, just what you convert them as.
The Libyan and the 2nd Tunisian pieces are better. The Tunisia was just recently bumped up in price but really isn't too special. Libyan coins are tough in unc and their economy is growing rapidly.
