<p>[QUOTE=&quot;ernstk, post: 4781794, member: 112998&quot;]I am still not convinced how patina layer is not absorbed into the metal. I cant see any azurite and malachite Crystals.&nbsp; These Crystal structure is hard to fake and can be visible under magnification and microscope. Based on my experience with Bronze items, the surface under patina would be very much more damaged than what I see in this image. there is not much damage on the base metal but if patina forms over ages you would expect to see much more damage and pitting under patina. You can see some LRB coins posted here in some threads after cleaning to see what type of pitting I mean.[/QUOTE]</p><p><br /></p>
