Nice blue toned brown ikes! and a steal under melt. Good luck trying to get them in a holder though if that is your intent.
That first one might actually make a good test subject for the acetone. On closer inspection, the second one may actually be starting to corrode -- it's clearly scuffed and fingerprinted, too. Don't know whether someone badly mishandled it at the Mint, or whether it was cracked and then glued. I could've gotten $19.20 for them at the coin show, a reasonable return on the $15.20 shipped that they cost. But I'll probably hang on to them, for now at least.
No, you wouldn't have -- it was a Buy It Now. Camp on the "recently listed" Buy It Nows, and you too can find bargains, if you're patient enough.
Again, they aren't blue toned -- they look much better in the photos than in hand. No chance of TPG, especially for the second one, which shows some serious scuffs and rim dings.
I see nothing that would lead me to believe that the coins could not get graded. Brown haze on 1971's is not uncommon. Blue and even Green haze on 1972's is also not uncommon. Often times, this haze may appear to be fingerprints and white streaks in photographs. No, they won't get 69 DCAM's but they'll grade.
