Actually no. That is a die crack that is now spreading like a chip, but no in the sense we see on the single squeeze dies. But because the dies were over used on the 1950's wheat cents, we see more of a breakdown on that decade. (1946 as also a bad year as well)
No to the question of more metal. The answer is no. The planchet starts out a certain weight and it doesn't get heavier unless something like a material, debris or something else is struck onto the planchet. A cud/mint mark/chips do not add weight to the coin. The metal is just rearranged like it is on all coins.
