[QUOTE="GDJMSP, post: 7491500, member: 112"]There's a very simple way to realize that simply isn't true and cannot even be true. And all one has to do is ask yourself a question. If the majority of the metal flowed outwards, then why are blanks run through the upset mill to make planchets ? The answer of course is because that's the one and only way there is to get enough metal at the outer edge to form the rim. Rather obviously, if the majority of the metal flowed outwards when a coin is struck, then upsetting the blanks would never be necessary. The fact that it is necessary tells us the vast majority of the metal does indeed flow inwards.[/QUOTE]
