2000 & 2001 Off-Center Strike

By definition, an off-center error must be missing a portion of the design on both sides. MADs(misaligned die strike)are more common and typically involve only one face although both dies can be misaligned in rare cases. MADs are typically seen with part of the rim missing and in severe cases of misalignment, a portion of the peripheral devices can be cut off at the edge. Without seeing the reverses, I would say that you have two minor MADs but they would not have a premium on them.
