<p>[QUOTE="Conder101, post: 4323038, member: 66"]I believe you mean the rim not collar. The collar is a heavy piece of steel that is the third die in the press and it creates the edge of the coin. The dies are supposed to centered in the collar but if they are misaligned one or both will be closer to the collar on one side than the other with the result being uneven rims, thin or almost missing on one side and extra wide on the other. The anvil die, because it in contained within the collar, can never be very far misaligned, but the hammer die can vary form almost perfectly centered to so far off that part of the design is off the edge of the planchet and the die is smacking into the collar with every cycling of the press. It takes a little time for the die setter to get the adjustments perfect to have the die centered so if he is a little rushed one or the other die is misaligned often enough that misaligned die coins are considered common and don't bring a premium unless they are far enough off that part of the design in missing.[/QUOTE]</p><p><br /></p>
