<p>[QUOTE=&quot;John Anthony, post: 2028407, member: 42773&quot;]Hey folks, this coin arrived today, and the green spots are, in fact, BD. But I bought it knowing full well that I might have to conserve it. I&#039;ve removed most of the BD as you can see from the pic, but the last little bit is stubborn. I find that a long soak in distilled water tends to loosen it up, and that&#039;s where the coin is now. This is not much of a problem as far as BD goes, and this coin is far too nice (and rare) to simply discard without some attempt at conservation.</p><p><br /></p><p>[ATTACH=full]368748[/ATTACH] </p><p><br /></p><p>Once the deposits are completely gone, it&#039;ll soak for another month, then I bake it completely dry. If a year goes by without a recurrence of the BD, I&#039;ll add a drop of copper darkener to the exposed bits of bronze.[/QUOTE]</p><p><br /></p>
