<p>[QUOTE=&quot;justafarmer, post: 548415, member: 3926&quot;]Most people on CoinTalk know that prior to 1990 mint marks were hand punched into working dies. Therefore the location and orientation of&nbsp; the mint mark from working die to working die is not at a fixed location relative to the other devices of a coin’s design. In fact I am of the opinion that the probability of two working dies from the same year having mint marks punched at identical locations in identical orientation relative to the rest of the design (which are hubbed into the working die from a master) is very small.</p><p><br /></p><p>Using a flatbed scanner would be a means for acquiring a standard image for plotting the coordinates. The coordinates is the important information afterwards the image is disposable.[/QUOTE]</p><p><br /></p>
