<p>[QUOTE="Hobo, post: 498665, member: 11521"]Business Strike Pres Dollars are made in a two-step process. In Step 1 the obverse and reverse images are pressed into the planchet (like any other coin) creating a coin with a smooth edge. In Step 2 the coins are fed through a machine that applies the edge lettering. The coins are run through that machine with no attention to their orientation. So about 50% of the coins will have the edge lettering applied in one orientation and about 50% will have the edge lettering applied in the other orientation.</p><p> </p><p>Proof Pres Dollars, on the other hand, are made in a one-step process where the edge lettering is applied at the same time the coin is struck. This is accomplished using a segmented collar what contains the edge lettering. After the coin has been struck the segmented collar opens up to release the coin. So all Proof Pres Dollars will have the edge lettering applied in the same orientation.[/QUOTE]</p><p><br /></p>
