Is the word cópias the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical usage of "cópias" are identical in both Brazilian and Continental Portuguese. The difference lies strictly in pronunciation (phonetics). In Brazil, the vowels are generally more open and the rhythm of the speech is more melodic and "vocalized." In Portugal, the pronunciation is more "clipped," with unstressed vowels being more closed or even reduced, creating a more consonant-heavy sound.
