<p>[QUOTE="robp, post: 5244236, member: 96746"]If you look at the brooch, despite there being no jewel detail left, there is still copper oxide(?) left within the circle. Looking at the olive branch or the A in the legend for example, some of the relief is wafer thin and thinner than you would expect, which is consistent with corrosion. The edge can now be seen to still have deposits within the finer detail. All those deposits are a result of the environmental conditions the coin was subjected to. How the deposits were removed is immaterial, because the loss of detail is down to chemical processes and that is where the damage was done. Nobody took an unworn mint state or close to coin and decided to tool it, whether by hand or with an electric tool. It was damaged to begin with.</p><p><br /></p><p>We'll probably have to agree to differ except on the point that it doesn't look good.[/QUOTE]</p><p><br /></p>
