Personal pronouns have two possessive forms. The forms mine, yours, ours, hers, his and theirs cannot be used before a noun. The forms my, your, our, her, his and their are actually possessive adjectives. They are always used before a noun.
Compare:
That coat is mine. (NOT That coat is my. A possessive adjective cannot be used without a noun.)
That is my coat. (NOT That is mine coat.)
