Italy began a great run of Neo-Classical coin designs beginning in 1908, and then with their commemorative coin series of 1911, on their 50th Anniversary of Unification.  The most commonly available, and very affordable, example is the 10 Centesimi of this one year type. At first glance the reverses look the same but the silver 5 Lire and gold 50 Lire feature a modern steam war ship rather than a wooden ship. Either way it's a bold, dramatic and iconic way to celebrate your 50th. There's a nice article on these coins, and others of Vittorio Emanuele III, in the Oct. 2020 issue of the "Numismatist."
