<p>[QUOTE=&quot;Clavdivs, post: 3622493, member: 93702&quot;]I was wondering if I could get some ideas on the differences between Patina and Toning when discussing ancient bronze coins... how it develops, etc.</p><p><br /></p><p>-would ALL bronze/copper coins 1800+ years old develop a patina? Or does this only develop when they come in contact with soil, water and/or other natural elements over the centuries?</p><p><br /></p><p>-if a coin was found after 1800 hundred years in a dry place - like say between two dry bricks would it not look mint state when found (after a quick wipe) or would a patina be present?</p><p><br /></p><p>-I assume toning is a reaction to the particles/gasses in the air? Is it the start of the patination process? Cabinet toning - I assume is from the off gasses from the cabinet&#039;s wood.</p><p><br /></p><p>Using my Probus coin below as an example ... do you think this has been stripped of patina at an earlier date and only started toning since then?... or is it possible this is a coin in its original state that was found as is.. only toning due to age/air/gasses?</p><p><br /></p><p>Obviously no one knows for this example .. but do we assume ALL coins in the state below have been stripped of patina??</p><p><br /></p><p><br /></p><p><br /></p><p>[ATTACH=full]971253[/ATTACH]</p><p><br /></p><p>Please add any nicely toned bronze coins.. and your opinion on this subject is very welcome![/QUOTE]</p><p><br /></p>
