I collect coins and tokens which circulated in Africa from 18th century to 2000. I sell about 7000 illustrated world coins from http://www.avscoins.com.
Even being silver, the Italian coins are very common and in this condition are hardly worth much more than silver value (about $6.25 today). The souvenir is probably not silver and is maybe $1 worth. So if you didn't pay more, then you did fine. Reselling them at a profit might be problematic, if the purchase price was not below bullion value.
