Your coin is the H (Heaton Mint)type. Unlike the other H types, this one has the H at the rim, not right below the date.
Most 1900 and 1901 cents are slightly concave on the obverse and convex on the reverse, leaving the queen's portrait with less wear than the other side. The bulge you see is caused by too much pressure from the obverse die, leaving an impression of the queen's chin between the 0 and the T.
Your coin appears to have corrosion among the leaves, and since it's not the scarcer no H type, it's not worth getting certified. Worth about $3 with that corrosion.
