<p>[QUOTE=&quot;wxcoin, post: 2698848, member: 74624&quot;]I like original looking coins but the fact is, older coins usually have some sort of toning due to the environment they were in or have been dipped.&nbsp; It would be interesting if someone could do a study of the location of where coins spent most of their existence (not only what they were stored in but also geographically) versus toning.&nbsp; Over time in an industrial urban setting does the atmosphere contain enough concentration of pollutants to tone a coin?&nbsp; Different urban settings have different concentrations of specific pollutants so would that have an influence on color?&nbsp; Maybe all of this is a reach; how they are stored determines toning.[/QUOTE]</p><p><br /></p>
