<p>[QUOTE=&quot;lackluster, post: 1258678, member: 21103&quot;]I know some of the basic topics are covered in other threads (which I will search through) however I would like some general info from those of you in the know.</p><p><br /></p><p>First off most of the coins referenced were bought in the late 70&#039;s thru early 90&#039;s.&nbsp; I know many are in the old PVC flips.&nbsp; All have been in the bank lockbox.&nbsp; I noticed some are starting to show discoloration although many are still as beautiful as the day purchased.&nbsp; I have my reservations about an acetone dip for coins that do not need it.&nbsp; I plan on transferring all of the coins to safeflips.</p><p><br /></p><p>I noticed the larger coins (silver $1 and some halves) tend to show the toning (discoloration) on the rims and generally near the top, I wonder if this is the result of an old dipping by the dealer or possibly something caused by the staple which is only in the top.</p><p><br /></p><p>A couple of the V nickels appear to be the worst (which I assume may be PVC damage or verdigris?)&nbsp; Some of the other coins which range from&nbsp; xf-sliders I feel that the coloration is the result of a prior cleaning of one type or another.&nbsp; Ironically most all of the old BU copper indians and lincolns are still beautifully red or nicely toned down and radiant.&nbsp; This is one thing that leads me to believe that the majority of the issues are with a coin that was cleaned prior to my buying it and is now showing the signs of that cleaning or dipping.</p><p><br /></p><p><br /></p><p>Even though I am hesitant to do so, some should probably have the acetone dip before being put in safe flips.&nbsp; Would you recommend doing only ones that show some sign of unnatural coloration, or all coins that have been in the old flips?&nbsp; I understand this stops the process but does not change the appearance or remove coloration, is this correct?&nbsp; If I simple transfer all coins to safe flips w/no acetone dip will the coloration worsen?&nbsp; (does this depend on whether it is PVC damage or verdigris?)</p><p><br /></p><p><br /></p><p>Any suggestions would be appreciated.&nbsp; I don&#039;t want to make a bad situation worse by damaging coins that have no visible effects.&nbsp; Some may simply need a silver dip to remove some unsightly tarnishing.</p><p><br /></p><p>I plan on taking a representation of these with to the OHIO state show on Sun to show to some dealers.&nbsp; Would like to post some photos if I can figure that out.</p><p><br /></p><p><br /></p><p>Thanks,</p><p><br /></p><p>Lackluster[/QUOTE]</p><p><br /></p>
