Now that I look at your original post, it does seem as if something has happened. Perhaps a chemical cleaning without neutralization?
Well I'm convinced that based on your reactions that this should not have happened from a manila envelope. Thanks for input.
Here is a 17' this is the same coin shot under different light setting different light positions and just a glimpse at how a coin can be manipulated by the photographer. If your coin conditions are less than satisfactory then please disregard the below photos.
Exactly why I started this thread....https://www.cointalk.com/threads/how-do-you-present-your-photos.351782/
Yes, it was absolutely dipped. If that first picture is the sellers, then it was dipped before you bought it. That bright, pink look is not natural. It is natural, however, for a coin to tone quickly after a dip as it begins to regain some skin. That cardboard holder is not an archival material, so it probably contains some chemicals that accelerated this toning.
if this is how it was stored for 3 months,this is not a manila envelope, its cardboard. Specifically Kraft paper cardboard, Kraft paper is made by using the "Kraft Process" and it involves wood chips being cooked in a sodium sulfide and sodium hydroxide mix to break down the lignin and separate it from the cellulose. the remnants of said chemicals of this process are in the brown kraft paper cardboard envelope or any other cardboard of this color really. coin 2x2s don't use this material. it is a cardboard, but not that kraft process. Manila envelopes are more paperlike and yellow to orange. Kraft paper cardboard is this brown color, just like kraft paper color is or most cardboard boxes. Cardboard 2x2s and coin storage is more of a fibrous cardboard and "grey" color which is less chemically treated. they use this grey cardboard also for shoeboxes and other items, because it's less harsh for longer term storage to the items inside. sitting in there for months absolutely will cause it to color up rapidly. If it was me, I'd let it run it's course and take pictures of it every 3 months and turn it into an experiment and make lemonade out of a lemon. this might produce some interesting color along the way.... or stop it right where it is and get it into something less reactive. all it's done is color up what was already existing on the surface making it more noticeable as it tones.
Thanks for explaining the difference. I did just let it go for another 2 months for a total of 5 months... it got worse for sure...But I've dipped and bagged it since. I couldn't stand to let it go anymore.
I think she's pretty, but letting it go further might get the darkness in lincolns coat and at the rim edge to go further and darken it out. Seriously I think it's got great eye appeal from these last pictures. the way the kraft paper is made, you really shouldn't store in anything that looks like brown cardboard color. go for the yellow/orange manila, if you have to do it, or grey cardboard with archival quality assurance if you can. it's all fine short term, a couple days a week or so, but long term in months to half a year or a year it can be a problem, but I guess you know that now. lol. And by "dipped" I really hope you meant acetone and not an actual coin dip to remove the toning....
