My new 1942 proof cent has the blues . . . maybe because I STILL need three more coins to complete the set 0

These are just quick pics off my iphone - it shows quite a bit more blue in-hand:

 

I still need 1937 and 1938 quarters, as well as that super difficult-to-find . . . 1968-S dime?!

Yea, not seeing the blue. Too bad, blue looks nice on those old coppers. Nice sets you have going there.

That's a lot of nice looking proofs.

Interesting, I was not aware that Dansco made an album for year sets like this, @James at EarlyUS.com what is the number of that album?   That is a very cool and fun set of sets that you have put together.

Blue is fairly often seen on 1936-42 proof cents. I am not an expert on those proofs, @RWB is. But there is also a gentleman in Millersville, PA (Lancaster County …. AGAIN!) who has literally written the book on earlier proof Lincoln cents, including but not limited to Matte Proofs. He tells me the packaging of those 36-42 proofs is responsible for the blue. This is TOTALLY different from the blue 1962 proof nickels, which are reportedly caused by excess cobalt in the alloy.

Thanks!  I've been working on it for ten years or maybe a little less.  My two guiding principles have been: Do not break up any existing proof set, and Try to use only non-certified examples.  Although I couldn't hit those goals at 100% (a few coins inevitably had to come out of slabs, like the proof Buffalo nickels), at least no complete proof sets ever had to be chopped up.

The album is a Dansco 7091 "United States Year Sets".  For my purposes, it fits all the coins from 1936 - 1969 in a nice, compact format.  The only annoyance is that pesky 1942 proof set that has an extra nickel, taking up a row all by itself.

It's in the Good Book:  "What [tetragrammaton] has joined together, let no man put asunder." This principle was cited by those opposed to construction of the Panama canal across the isthmus and presumably, by extension, applies to unauthorized decapsulations and breaching the integrity of proof sets.  I don't have to read another word. You, my friend, are my kind of collector!  😉
