Yes the Albert coin  Belgium   have a premium  cos they are 250000 minted  125000 belgium  125000 flamish , also the leopold  1865  .You can get for small premium  the Austrian 20 francs  and the  Hungarian one . The Emanuele  III have very high premium at least double the gold value .
The 20 lire from 1859  dawn have a big premium  , the  20 francs  French are easy to collect  from 1848 dawn they command a premium of 30 to 50 euro   but you can collect  them  compared to the Italian ones   which are very expensive  some dates cost over 500 euro
The rest of them have big premiums and is  hard to find one  for a decent  price
