The images (in sunlight and axial lighting) cannot capture the vibrant rainbow colors circling the obverse rim. Ike's portrait has a range of colors, moving from light gold on the face to deeper gold and purple beyond the hairline. The reverse is more consistently gold toned, though the fields are richer in color--which highlights the DCAM effect of the Liberty Bell and moon. (Note: The yellowish tint on the left obverse is a reflection off the plastic slab; the other colors are accurate.)
Now, for all that color, it's a PR69DCAM. Sure, there are a bunch of toned Ike proofs in PR68 and below, but PR69--and DCAM to boot? Also, consider that it's a Type 1 Clad: In my experience, that's a tough coin to get in a clean, handsome, consistent tone. Their toning tends to be foggy, which reduces the mirror finish. Not this coin: Both front and back show lustrous mirrors. What's not to like about this coin?
This is an early PCGS slab, so any scratches are on the plastic surface, not the coin.
So, how unique is this specific coin? Besides for my own entries, I find no eBay listings--neither active nor recently sold--for a toned '76 S Type 1 Clad PR69DCAM. My "buy it now" price reflects the scarcity of this coin type in this condition with this toning.
