<p>[QUOTE="Bill in Burl, post: 1525076, member: 23692"]The photo and the crud make it impossible to tell you which of the 27 Obv working dies struck your coin, nor any of the reverse dies for the same reason. You have a VF example of a pretty good coin, struck fairly early in the mintage cycle. Since you have a full vine at leaf 7, it is one of the 16 Reverse working dies that struck this (after 16 damage occurred to the hub) .. after that, the hub broke at leaf 7 (leaves are CW from 12:00) so all others will have the start and finish of a break in the vine there(it gets larger with each new die made). Although the books in the past have put the mintage at 421,000, newer research (most by rob Turner and his books) show the 1858 mintage to be about 1.5 million. Your crud on the coin does not appear to be the hard green corrosive kind. Try some acetone if the crap is fairly soft (it will not hurt the bronze if used and moved gently with a cotton swab or very soft toothbrush. You will have to practice on much less valuable stuff first. Gentle, gentle, gentile and be sure to rinse with distilled water. I think that it is PVC or a chemical exposure similar to it that caused it, rather than buried. Once you get it, send me good photos and I'll tell you which dies it came from and the approx percentage of the coins that the die struck. All '58's are keepers.[/QUOTE]</p><p><br /></p>
