<p>[QUOTE=&quot;justafarmer, post: 206347, member: 3926&quot;]When attributing RPMs remember - S-L-O-M - (spread - location -orientation- markers).</p><p><br /></p><p>Spread - is the secondary mint mark (north, south, east, west...etc.) of primary mint mark?</p><p>Location - where is the primary mint mark located in relation to other devices on the coin?</p><p>Orientation - is the primary mint mark straight up 12:00 or rotated clockwise or counterclock wise?</p><p><br /></p><p>Once you have made the above observations you can attribute 90% of the RPMs. You only need to resort to markers about 10% of the time.</p><p><br /></p><p>In some years there are design features that will aid in attribution such as - 1960 Lincoln Cents (Small date, Large date), 1944-S, 1945-S, 1946-S, 1947-S Lincoln Cents (Mint Mark Style), 1982 Lincoln (Copper, Zinc), 1945 Mercury (micro s), 1878 Morgan (Tail Feathers) and etc.</p><p><br /></p><p>The above is the standard process - mine is slightly different L-O-S-M (Location, Orientation, Spread, Makers). I take a picture of the RPM and import it into TurboCad then determine location and orientation first. This is all that is needed about 98% of the time. About 2 times out of 100 - I resort to spread - which helps about half the time. </p><p><br /></p><p>Unless of course - its an RPM such as originally posted in this thread. It may not be classified as a Cherrypicker - but it certainly is one that is classified as easy-pickens (IMHO).[/QUOTE]</p><p><br /></p>
