film containers - okay for storage?
I don't know what plastic is used in film cannisters, but don't take a chance on it. Use products specifically made and tested for coins. You'll be ahead in the long run. Alan Herbert The AnswerMan |

In article , Chrysta
Wilson spoke thusly... In article , says... I don't know what plastic is used in film cannisters, but don't take a chance on it. Use products specifically made and tested for coins. You'll be ahead in the long run. Alan Herbert The AnswerMan I wouldn't take the chance, either, when coin tubes made for the purpose are so cheap, and so lightweight that shipping should be cheap as well if you buy them online. I agree with both of you and wouldn't take the chance myself. Related story, though... My Grandfather left me a bunch of coins when he passed away. They had probably sat in the same box since the late 70ies in various containers. Some were in well preserved state and others had seen damage from the storage. The extra stuff that he considered a hoard and had just dumped into pill bottles and an old glass Jiffy peanut butter jar were very well preserved. Wanna know what was the worst damaged...the coins that he had considered his collection and had lovingly placed in those damn Whitman folders. -- Stu Miller Read about Coins in the News: http://www.thestujoecollection.com/news.htm Director, RCC Mint http://www.TheStujoeCollection.com/rccmint |

Or you could run a sample through a mass spect and see what kinda reading
you get ;-) "Phil Barnhart" wrote in message om... Probably not. Only one way to be sure. Run the "Beilstein" test. Take a piece of copper wire and heat it in the blue flame of a gas stove, bunsen burner or acetylene torch until it glows red. then place the hot wire on a tiny piece of the plastic (the plastic will melt on the copper). Place the plastic/copper melt back in the flame. If the flame turns green or "azure", deep blue/purple, after the initial yellow burn, the plastic has chlorine. If only yellow is seen your flip is chlorine free and probably acceptable. Copper chloride formed in the flame is responsible for the distinctive color. Found a nice web page that goes over storage issues: http://members.aol.com/enidmac/16a.htm "David Axt" wrote in message ... Is it okay for storing coins in those translucent white film containers? I read somewhere that PVC is bad for coins. How do I tell if the plastic is PVC? Thanks, David |

Alan 'clam sauce for Morgans, tomato for cents' I had a very black buffalo nickel soaking for some months in olive oil. It lightened it but I don't think it helped it. It is now a very dark grey. Maybe another few months would help. I have seen a few black buffalo nickels off and on for over 30 years and don't understand what happened to them. Dale |

for over 30 years and don't understand what happened to them. A key reason for the color may be silicon in the alloy. This will turn nickel black. The silicon is found in the nickel ore and is difficult to remove. Alan Herbert The AnswerMan |
