<p>[QUOTE=&quot;-jeffB, post: 24620765, member: 27832&quot;]Baking soda and a toothbrush will work, but for that number of coins, I&#039;d be tempted to try a white vinegar soak. That&#039;ll change the color of the coins (making them bright orange/pink), but it <i>should</i> dissolve the corrosion a lot faster than it attacks the rest of the coin. They&#039;ll be considered damaged afterward, but they&#039;re already damaged, so no real loss.</p><p><br /></p><p>Whatever you do, try it on a <i>few</i> of the coins first, and see what it does.</p><p><br /></p><p>Also, that green stuff is somewhat toxic. Wash your hands when you&#039;re done; it might be a good idea to wear gloves, just in case you&#039;re subject to contact dermatitis from these sorts of metal salts. Flush the waste down the drain with lots of water.[/QUOTE]</p><p><br /></p>
