    Well a friend of mine was recently looking to purchase the 2015 dimes from the March of Dimes set. He said it’s amazing how many have a brown toning to them now. I wonder what’s causing that? So I told him I bought that set that year and had it stashed away in a climate controlled place.

    I took my set out today to examine out of curiosity.

    As you can see, mainly where the backing of the velvet flap has been resting on the what I would call “pot metal” underneath, there’s active corrosion after 7 years. So I took them out of this. No brown toning on the coins. The RP has a little hazy spot on cheek that would probably make it a 69. The other two could probably grade out at 70s.

    Just fyi if you have this set. I doubt any long term R&D testing goes into this stuff to see how materials will interact and they’re not going to use aluminum because it might cost a few pennies more. Its ridiculous. At least the back of the velvet holder was enclosed. I will leave them in that and store it without the clamshell.

    Good thing you checked. I have several silver coins from the mint, that came in the blue velveteen display and they tone in a very short time.

    Just checked mine. They appear to be absolutely perfect.

    Was your box corroding?

    The Mint used that blue velveteen on many of the their coins. Does anyone know if there has been damage on more recent coins?

    That is what you get when the government uses the low bidder.

    Quantity not quality. Seems to be the U.S. Mint's motto for some time. I've voiced this very matter over the past few years, by e-mail/actual letter and telephone to no avail. Simply put, they do not care.
