Who likes purple, rose, gold and green on their 1950 proof Lincoln Cents? Picture attached

Very pretty for sure great color!!
HAPPY COLLECTING
Wow! Crazy and nice.
that has the "look" of a coin that was treated with MS70.
That was my 1st thought, but in hand the iridescence leads me to believe otherwise.

Definitely an unusual color.
Al, could you provide more specific identifying characteristics of the toning of coins treated with MS70?
...yeah...show us how you do it please?
Brown copper swabbed with MS70 tends to turn purple with reddish highlights in close areas like lettering near the rim.
Very nice indeed!!
Thanks Al. I think I have coins with this characteristic in PCGS plastic? I might MS70 a PR Lincoln and let tone for future reference. Bluish with red highlights seems to be very common.
Nice.
From my experience with MS70...the toning comes immediately. You don't need to wait at all.
ditto what the 'crewman said, there's no waiting involved. if you search there are quite a number of threads about its use dating back to around 2003.
I usually see dark blue or dark purple on brown copper that's been touched by ms70. The more vibrant colors come with red copper touched by ms70. I also think the colors are more iridescent if the copper has some luster left IMHO.

Based on my experience with copper and MS70 (years of testing AT processes), based on those pictures, I would aggree with Al, it has been treated. Cheers, RickO
