What is the plural of my and mine?

The possessive forms of you are your (used before a noun) and yours (used in place of a noun). The reflexive forms are yourself (singular) and yourselves (plural).

Is mine a real word?

Mines is a dictionary-recognized word, but only as a plural noun (They sentenced the criminal to hard labor in the mines.) At the school where I used to teach, however, it was common for students to use this as the first person possessive pronoun: Me: Whose pen is this? The word is simply mine.
