AndisCoins New Member United States 18 Posts	Posted 01/05/2024 3:31 pm Hi everyone! I have heard different things about the storage of early US copper coins (such as Large Cents). I've seen suggestions for keeping them in 2x2 cardboard flips and other suggestions for using 2x2 archival envelopes with cotton liners. I've also seen suggestions like coating with a thin layer of mineral oil (Blue Ribbon?) or treating with Verdi-Care before storage to prevent additional damage. I'd appreciate any suggestions and/or links to previous threads on the subject. I've read through some past threads, but it's still not clear to me what the advantages versus disadvantages of different storage methods are. I mostly have low to mid grade specimens, but I'd like to preserve them the best I can as I enjoy them and protect them for the future! Report this Post to the Staff

Spence Moderator United States 34393 Posts	Posted 01/05/2024 3:39 pm @andi, you'll see that I've moved your thread over to the supplies subforum. I did this because it seems like the nature of your question is around storage supplies rather than the early US coppers themselves. If it seems like you aren't getting enough eyeballs on your question, then I'll think about moving it back. By the way, every one of mine that isn't slabbed is in a 2x2 with flattened staples.

AndisCoins New Member United States 18 Posts	Posted 01/05/2024 3:51 pm I assume that "airtight as possible" is probably a good bet. However, I know that some "Early American Copper" collectors use cotton liners in paper envelopes. This obviously leaves the coins exposed to air (and thus further oxidation). I'm not sure if there is a reason behind this. Copper is very reactive with environmental conditions (humidity, oxygen, acids, etc.), and I imagine some of the earlier coins might not have as pure or well defined alloys as recent coins. Therefore, I'd assume limiting exposure to air would be a good thing. Report this Post to the Staff
