Colorfully Toned Proofs ... Toning Inside (Original) Mint Sealed Cello

It's interesting when you see coins take on wild and vibrant color inside sealed (original) U.S.Mint cello packaging. I have never seen a blue toned 1964 proof lincoln before -- I have seen that color toning on other years though (especially 1961's), but it's rare on 1964's. It just makes me wonder what might have caused something like this? Impurities in the alloy? I have no idea. Since it was sealed, I have to think that environmental factors would have to have been greatly diminished. (By the way, robec did a stunning job with the photo.) (A final note that this was a "freebie" coin from Shane at KryptoniteComics, one of the top toned coin sellers on eBay ... Thanks Shane!)


Here is another one. A monster toned Jefferson nickel that toned inside the original cello proof set packaging. This is some of the best color that I've ever seen on a Jefferson. And it's interesting to note that none of the other coins in the cello packaging toned, they were all their original mint-fresh color -- just the Jefferson Nickel toned. Why? It's beyond me. (Once again, robec's photo is stunning.)

<< <i>if that's true ... why didn't all the coins tone? why did just one tone? >>
Not all the sides of the cello are airtight around all of the coins or in between coins. In your case, a small opening was between the coin and the outside environment. Or, some gases trapped inside the individual pockets of the cello reacted to the coin's surface. Not all coins have to be affected by it as (overstating the obvious here) their different compositions of metals.

This is another cool example ...

Most B&Ms have a box or two FULL of these, and most of 'em don't mind you looking through. I'll admit though, it was a lot more fun when you could buy the sets for $10 a piece. Now the silver alone is worth about 22x face, and most dealers want about $25 for these sets. Still fun when you find a good one

Edited to add, I'm sure there were these flee market dealers everywhere!

Some store their coins in safes, others out in the blazing hot sun. Kind of funny
