Yes, this word is used in English, but it a slang word. It is only used in certain circumstances. Exmaples: An "oldie radio station" is a radio station that plays music that is not popular now, but was popular years ago (usually 20-50 years ago). There is an idiom, "that's an oldie, but a goody!" meaning, it is old but it is still worth something. You could say that about a car, or a song, or a favorite game. You could say "it is an old car, but still a good car" or "it's an oldie, but a goody" and point to the car. In this case "oldie" is used as noun to mean "the old THING" rather than as an adjective "old". There is a phrase "a golden oldie" which refers to a song that used to be a hit records many years ago. (A "hit" is a record that is extremely popular, and earns a "gold record" which is a music industry award for having sold 100,000 copies of the song.) So it's "golden" because it was widely sold, and it's an "oldie" because it's an endearing term for something of that era.
