I agree with ND...ICG gets a bad rap for coins graded 67 or higher, but for circulated coins, they (in my experience)are very conservative. PR69 and PR70 1964 Lincolns are pretty common in all grading circles. Now find a PR68 or higher 1970-S Lincoln in CAM or DCAM...now you are talking!
Also, I like to keep up with the services on Grey Sheets:

ICG is always up there with both PCGS and NGC. Also, ask for James Taylor when you call ICG. He has always responded to my questions concerning the same issues you presented. BTW, take that PCGS PR70DCAM to a show, break it out (which I don't advise) or cover up the grade and PCGS themselves will probably grade their own coin PR69DCAM 9 out of 10 times.
If you want to contact ICG, here is their contact link. Ask the same question and let us know how it turned out:
