A Very Cool Cent Roll Search

I got 30 penny rolls the other day at one of our local banks here in town and to my surprise one of the rolls looked really odd. It was a wrapper I hadn't seen in a long time - pinkish-salmon color. My first thought was that it was just an old roll that someone had already gone through and there would be nothing but throw-aways. To my surprise, there were some beauties in it! The newest coin was 1984 and the oldest was a 1969 D. I found about a dozen 1982's in beautiful condition and 6 of them were small date zinc. 5 of the 6 small date zincs seem like they were fresh from the mint with no signs of wear. What a find!

I know "red" Lincolns carry a premium, and the 5 zincs look much different or "redder" than the others, is that because they are zinc, or is there a good chance they are red? I can supply pictures if needed, but I figured this might be a common occurence/question about this particular coin. Any help would be appreciated.

Thanks,
Chris
