Jefferson collectors, how rare or common are.......

........ pre 1971 Cameo proofs with two sided, multicolored attractive toning?
I was looking at some of my frosted proof Jeffersons tonight that have been stored in late 60's OGP and noticed that many have developed attractive blue and golden toning. They have lots of eye appeal.

They aren't really rare but sell for strong prices if the colors pop.
If they're the run-of-the-mill blue/gold you'll do ok on them, but the violet, yellow, magenta and orange ones go for more.
Post pics! It depends on the year and quality.

If it has colorful tarnish, there is a market.....

Here are two of the coins. Photos taken by my phone. They look much better in hand.
Nice looking. From pics maybe they would get cameo designation, not deep cameo on my opinion, but I'm no expert. I paid less than $20 each for my pcgs graded pr68cams. Which is less than grading fees. But mine have no tone

Do these come from the blue cardboard proof sets? I do not see enough color from your pics to give any premium.
The two coins came from 1968 and 1970 prroofs sets in OGP. The photos are not very good. The coins have two sided heavy frost on the devices and mirrored fields. Qithout the toning the coins would like receive a Cameo designation. The toning on both coins is primarily golden and blue, however there are hints of other colors mixed in. In hand, viewed under good lighting the coins have fantastic eye appeal.
