<p>[QUOTE="Conder101, post: 444002, member: 66"]A broadstruck coin is a coin that is struck without the collar in place. When a coin is struck the pressure from the die akes the metal expand outward radially from the center of the coin. Normally there is a collar aound the planchet to restrain this expansion, create the reeded edge if any, and to force the metal upwards and form the rim. If the collar is not present because it gets jammed down around the lower die the coin expands outward to a larger than normal size. How much larger depends on the force of the strike, the metal the planchet is made of, and how well annealed the planchet is.[/QUOTE]</p><p><br /></p>
