Jbuck has it, longer die life and high speed presses You coins used to have a die life of 200 to 500 thousand, now it is closer to a million, Coining speed used to be 30 to 60 coins a minute or one to two per second. Today it's 750 coins per minute or 13 coins per second. When the metal only has .04 seconds to fill the die recesses you don't want the metal to have to move very far at all. Hence lower flatter relief.
