Random Riddle: My Face

I wear the face of a leader of men.
My financial worth is small and my appearance not impressive, yet my presence is a passport to any country and society.
I have the entree alike to the boudoir and the armed;
I penetrate to royal palaces and to the far corners of the earth.
In my youth I am bright and fresh looking; later, my face is marred and disfigured, and I am cast aside as nothing; but when I am very old I am eagerly sought, and a safe refuge is provided for me, where I am exhibited to admiring visitors.

What am I?
