Now I have to go look at my sets. I think I have Mint sets back to 1950 (it's been a long time since they've seen the light of day and my mind is a bit fuzzy -- age thing).
Has to be more to it than that. All of them from '47 thru '58 had the same holders, but only the '58 is really known for spectacular toning. Sure it happened with other dates, but only in isolated cases.
57 is also found spectacularly toned, as are occasionally the 56s. I suspect the type of cardboard these coins were shipped with (and the sulfur contained therein) caused the toning. It would be interesting to do some research to see if the sourcing of the cardboard (or the manufacturing process) changed over that time period.
I can't get a good picture of the Reverse. The other Franklin is blue on the obverse and other colors on the reverse (but nothing like that quarter). The cents arent picture worthy, and the nickels arent too bad - one of them is also blue (lot's of blue coins, which I like). Here's the other quarter. Unfortunately the obverse has that non-lustrous toning The other dime has this type on the entire obverse, but the reverse is nice, which makes it look strange.
Holy cow Mag, whered you dig this set up? First I have heard of it, and WOW, nice one. Bring it to the show in Scottsdale Sunday and let me see it in hand, you might want to placticize some of them
Oh yeah, I'll bring them by And just like I said, I may want to send them to NGC (possible Stars?). We'll see. Also, I'm going to send that crazy Frankie to Todd (where Charmy sends them) to get a good photo taken, because as we know, toners are super hard to take a picture of.
Thanks and I know, but my photography station is my camera, hand, and window open, lol. I'll just pay the pro's to take clear, straight (non angled) pics.
