Just wondering has anybody seen toning like this in an unopened mint package. Actual color is red/brown. Its strange the half and Quarter show this but the dime is pristine.

I have never had any myself but I have seen plenty advertised as having Mint Set Toning, especially Franklins. I imagine it is not uncommon.

I have seen coins toned much more then that in mint packages...don't know what causes it...but the color i se most from mint packing is a red color...

Just caught me off guard. None of my other sets have any toning, at least like this.

dime from same set.



nickel same set solid golden tone (Seen this several times)



penny from same set

that nickel toning is fairly common. That lincoln looks awesome gold-toned(may be the lighting?) . There's always the possibility that the planchets used for the dimes were "cleaner" or "fresher" than the silver planchets for the halves and quarters.

The penny is nice and gold. The pictures are pretty close on it.

That makes sense on the difference.

Great looking set though

I had a '62 set which I cut, and both the cent and nickel were the same as yours. The silver coins were unblemished, though.

My eyes are crossing now. I've drug out all the mint sets and looking at them with a loupe.

I can't see the pictures but I've seen many Jeffersons with a gold tone and some with a blue tone in mint and proof sets from the 60s-80s.

I've always held the theory that toning within the sets is caused by:

1) impurities on the plancettes -- could be grease from the press or breath from a worker

2) air leakage into the packaging -- some compartments may allow air/moisture in while others are fully sealed.

3) impurities in the packaging

Combinations of the above.

I can see the pics now.

Shame I can't get a picture of it. I tried but it did not show. But I found a 1971 s clad dime inside a proof set with a bit of the copper showing in the field.

Yes....very common to find toning in 60's proof sets. I have purchased hundreds of sets looking for toners instead of Cameo's and 1 in about 10 sets have some descent toning.......usually on the Nickel but not uncommon on the Silver Coins. In my experience the toning is caused buy the outgasing that happens when the plastic starts to break down. In almost every case I have seen the packaging that contains toned coins is starting to deteriote and even come apart in some cases.

Here are two coins I pulled out of a 1961 Proof set and I have another 61 proof set still in tact with some nice toners in it.






Bpth of these coins were originally bodybagged by NGC even though I cut them out of the plastic myself. I sent them back in for review and they promptly graded both free of charge.

The toning, for me, of the proof sets are either fantastic or horrible. Seems to be no middle ground. Although the ones posted above (all in fact) would sit favorably with me and my collection.
