<p>[QUOTE=&quot;moonunit, post: 3979368, member: 109522&quot;]Sorry for the long post, but to to make a long story as short as possible, as a new collector I took a bit of a risk and spent a decent amount of money to buy a (semi-)mystery set of coins at auction. As a result, I am now the proud owner of roughly 500 coins from (mostly) occupied areas during the World War II years. Think Vichy France, Japanese Puppet States, etc. On the plus side, after researching them, the coins are worth much much more than what I paid. On the negative side I’m interested in very few of them, so I’d like to sell most off and many of the coins suffer from being coated in gunk from long term storage in PVC. Some have actual PVC damage.</p><p><br /></p><p>With all that in mind, I was hoping to get some advice on best sale tactics under the circumstances. As far as I see it, I have two sets of decisions to make: A) sell to a dealer OR try to sell myself on ebay, B) try to remove the PVC using acetone and repackage the coins before selling them OR sell as is.</p><p><br /></p><p>I am heavily leaning towards selling to a dealer. I know I won’t get as much as if I sold individually over time, but I also am relatively new to the hobby (so I’m not the best at grading), have no ebay presence, and selling this volume individually or in small groups sounds like a real hassle. But I’m open to arguments to the contrary.</p><p><br /></p><p>The real thing I’m questioning is how to handle the PVC. I assume that bringing in a whole bunch of coins that are coated in green to a dealer would significantly reduce offer price, but by that same token so would my attempting to fix each one on my own and messing some up some percentage of the collection in the process. So all things considered what should I do? I’ve read countless threads where people say 100% acetone is harmless to metals. But in my experience while most coins do fine after getting a quick bath, copper can turn purple and I’ve had some selective bronze coins develop what looks to be bronze disease that wasn’t there at all before very quickly after plopping them in a bath, with increased exposure making things worse. If the answer is to take a risk with an acetone bath, given that I am dealing with lots of off-metals (aluminum, zinc, tin, iron, lead, brass) is there a list of rules for which metals/alloys are truly acetone safe, which are a risk, and which truly aren’t? If a coin is plagued by PVC and not acetone safe are there other options? The one upside here is that I do have a lot of coins from the same series, so I could always test some out and discard if there are issues, but I was hoping to sell the set as intact as possible.[/QUOTE]</p><p><br /></p>
