<p>[QUOTE="Lehigh96, post: 2421774, member: 15309"]I think that the large majority of Morgans that show toning are bag toned Morgans which will show a rainbow progression on one side with the possibility of minor toning on the reverse that will have the correct toning correspondence. For example, this Battle Creek 1886 shows the deepest toning on the obverse at 4:30 while the reverse shows the deepest toned are at 1:30 showing perfect toning correspondence.</p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Morgan%20Dollars/MorganDollar1886NGCMS65StarBattl-10.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><br /></p><p>Bag toning comprises the majority of toned Morgans on the market, but that doesn't mean there aren't Morgan Dollars that were toned due to different storage methods.

It would be rare for an EOR coin to have toning on both sides since the one side is protected from air flow.

However, coin folders can cause a coin to form a more consistent monochromatic toning pattern and less of a target toning effect.
