Can i still use stamps from 2001?

Question

they say USA 60

Answer 1

Does it say 60c? As in, 60 cents?

If you are mailing a standard envelope you should be fine.... even for a standard sized envelope (like one you might put a birthday card in) you only need a 42 cent stamp as long as it is 1 ounce or less.

Answer 2

All stamps but one issued by the United States since 1861 are still valid for postage.  (The exception is a 10-cent Christmas stamp from 1974.)

Answer 3

is it this one?

On Sept. 25, 1995, a 60¢ stamp depicting aviation pioneer Eddie Rickenbacker was issued. Although the stamp fulfilled the overseas half-ounce letter rate and featured an aviation theme as did past airmail issues, the stamp was not inscribed with the word "airmail."

Yes, you can use it.
