Is old Italian Paper Lire 1000 worth anything?

Yes. One thousand Italian lire banknotes are worth something depending on their age, condition, and serial number. Some of these banknotes can fetch a high price among collectors. For instance, a 1983 "Caravaggio" 1000 lire banknote in uncirculated condition can be worth around 20 euros. A rare 1963 "De Gasperi" 1000 lire banknote, also in uncirculated condition, can even be worth over 100 euros.
