In addition to what TomB posted, matte proof Indians were only struck from 1908 through 1915 in very small quantities. I believe the total mintage for all 8 years was under 2,000 pieces.
If you came across an impaired proof that had been circulated it would be very difficult to authenticate without knowledge of die characteristics.
