Looks like today's standard "frosting" (pebbling), which trashes the design's fine detail. I remember a thread where someone posted examples of (I think) proof Lincoln cents showing the change over the years as the mint's process "evolved". A shame, but I'll withhold judgement until I see it in-hand (tomorrow, if tracking is to be trusted).
Her hair looks like some tangled rope. Just another coin with hair blowing and a eagle. They all get to lookin' the same after a while. Seen 'em sell well below issue price on Ebay. One sold for $1240 the other night. Issue price $1350....and platinum is dropping. BUYER BEWARE !! STAY AWAY FROM RECENTLY ISSUED MODERNS and UPCOMING MODERNS. MOST ARE BOUGHT BY FLIPPERS, MCM, APMEX ETC. ETC. Gonna make $$$ off you. To the true collector of these, I'm glad you got one at cost and didn't have to pay a flipper twice as much for it.
So many iffy facts here. Can you provide the auction that sold that cheap? Cheapest I see is over $100 higher (even though I still consider that a flop). And platinum is up over $100 in the last 30 days... I would calling that rising, not dropping.
I knew that would fire you up Witten. I was wrong on the $1240 price, it sold for $1259. Ebay item # 252449393181. There's another for $1276 and a few more under $1350.
Ahh, I found it. That was poorly listed. They didn't even have "Eagle" in the title, which is what the coin is. It was not showing up on my (or probably a lot of other) searches.
Not very familiar with the series, but is the Mint not planning on putting out a business strike? I'm not a big fan of all these new frosted proofs.
