<p>[QUOTE=&quot;gsimonel, post: 3231087, member: 82549&quot;]The graininess on the first and third bronze coins is probably due to corrosion and the harsh cleaning that it took to remove it. The middle bronze is definitely not cast--what would be the point? I can&#039;t say anything certain about the silver coin. I do see some tiny circular bubbles on the reverse to the left of the A in the middle of Alexander, but I don&#039;t think that&#039;s enough evidence to condemn the coin. Perhaps much of the coin was covered in that black stuff you see in places on the reverse (silver nitrate?) and chemically removed, leaving the grainy surface.[/QUOTE]</p><p><br /></p>
