<p>[QUOTE=&quot;Factor, post: 25563297, member: 96413&quot;]I have several coins from them. All have very artificial patina. They probably do some harsh chemical cleaning in bulk, and after that glue on fine sand, also in bulk. But I keep buying from them, some coins are rare (like one Victor posted) and if I can&#039;t get a better example it works for me. Definitely not for everyone. My main concern is that this initial harsh chemical treatment will cause some bad reactions (like bronze disease) and artificial patina will mask it until it is too late to treat. So far I didn&#039;t see it, but I don&#039;t have them for very long.[/QUOTE]</p><p><br /></p>
