No, not worth the expense. It's way cheaper to let the big companies do this looking for the PR70's and then buying them after the fact dirt cheap. I put together a run of Jefferson nickels this way in PCGS holders in PR69 for less than $4.00 each. Talk about fire sale prices.
Would you by chance have a picture/photos of the difference in these two? (ASE) I have a couple 2008 and never pursued it. Thanks.
My understanding is this variety occurs on the 2008 W Burnished ASEs and it can be detected easiest by looking at the U on the reverse. The 2007 had a smoothly curved U and the 2008 has a spur or foot at the bottom right.
Looks like this blind squirrel...oh wait...I read that in the Silver Eagle book. It's a great resource and very helpful for the ASE collector. Stackers can skip it and spend the money on their stack.
Lacking the book (which I do not), here's a nice online site to help........ http://silvereagleguide.com/mintages/ And this one (though it hasn't been updated in a few years)........ http://americansilvereagles.us/
2005-S KS Silver Proof SQ, FS-901, Die Dent - NGC PF70UCAM - Top Pop Chris NOTE: These photos were taken before this variety was added to the CPG in 2012. Disregard all of the flecks of cardboard dust because the first two photos were taken in the Mint case.
If you had a proof coin with a variety where only 12 were known to exist and someone offered you $1,000 for that coin only, would you change your mind? Chris
Also the tilde between "SILVER" and "ONE" on the reverse is different, and the stars above the eagle are spaced differently.
Last year I sent my mint-fresh 2015 Platinum American Eagle for grading. If it had graded PF70 (it didn't), it would've been worth ~$1,000 more than a PF69. Worth the submission cost based on populations. And really, what's the downside? But that coin is an exception. I've never done it with other modern coins and don't plan to. Although, I might submit a 2016 Platinum Eagle if I get one and it's low mintage and it looks good enough for PF70. Maybe this year's Centennial gold too?
Perhaps I misunderstood, but this sounds a bit contradictory. If you wouldn't crack open the set with a valuable variety, then why would you look for another with a normal specimen? Chris
