<p>[QUOTE=&quot;GDJMSP, post: 24603485, member: 112&quot;]I can easily see keeping them for sentimental reasons, but even those that show the least corrosion, they are permanently damaged by the corrosion. Verdi-Care might help a few of the least corroded a tiny bit but it would largely be a waste of time and money. Short and sweet there is no safe way (defined as not doing any further harm) to clean them.</p><p><br /></p><p>But if you wish to keep them for sentimental reasons, and want to remove at least most of the corrosion, get yourself a still bristled toothbrush, dissolve a tablespoon or so of baking soda in a couple ounces of water, dip the brush in it and commence to scrubbing, with vigor. </p><p><br /></p><p>Once they are as clean as you can reasonably get them, dry them all thoroughly and then place them individually in PVC free flips. Store them in a sealed container like Tupperware, place a 40 gram rechargeable silica pack inside the Tupperware with the coins, and then store that someplace in your home where the temperature remains fairly constant. </p><p><br /></p><p>Do all of that and they should remain as you see them for years to come.</p><p><br /></p><p>Don&#039;t do it and corrosion will eventually literally eat the coins up. It&#039;ll take years but it will happen.[/QUOTE]</p><p><br /></p>
