This is a handsome Ike proof, near-flawless as the PR69 grading suggests. I had to restrain myself from cracking this coin out of the slab and putting it in a "themed" album of red-toned Ikes. (It's my folly, but that's how I prefer to view coins--all close-up and gathered together nine-at-a-time per page.) 

This particular Ike is a rare bird on eBay: As of this listing, there was only one other toned '71-S PCGS PR69 for sale (and at a considerably higher asking price, I might add). Given the quality and the rarity, my "buy it now" price includes a premium for the toning; that said, I think my ask is reasonable.  

I'll supply more images if requested.
