ASE Pricing Difference

well one is graded and the other isn't. The one in the OGP may grade MS-69 (which would be a 30.00 coin or so) but the other was graded a perfect 70 which means it should have no marks at all post mint and be a full strike. 70 is the highest grade you can get and most all proof coins will grade at least 68 with most 69 but if it grades PF-70 it means its perfect in the eyes of the grader. A normal collector may never be able to tell the difference between the two and usually the ones that pays the premium for the PF-70 is working on a registry set where as they will have a Top Pop coin since there can't be any higher than 70 so they never have to worry about anyone having a higher graded coin for that particular spot.
first strike is just a marketing ploy created by the Third Party Graders, there is nothing special about First Strike coins than any other coin that isn't marked as First strike, except for the date that the coin was shipped to the customer. Every once of that series may have already been minted before the first coin has shipped and you may get sent the very last one struck and if it was sent to you within the 30 days(I think it is) of the day they went on sale then it qualifies as first strike. The mint has a article about this ploy on their website here http://www.usmint.gov/consumer/?act...#firstStrike

Thanks. That clears it up a bit for me. What was confusing is I was assuming ALL proof ASE coins issued by the mint were of the same grade, i.e. perfect--PR70. To me, that brings up the question of what makes the difference if it's still encapsulated in the OGP. Can't be handling/exposure by whoever happens to own the coin since the coin itself hasn't been physically touched. Must be the mint. Not necessarily something they are doing wrong but something they are doing "different" for the ones that qualify for the PR70. Or is it just something inherent in the minting process that no one has any control over?

I'm not sure why, but another assumption I was wrongly making (given your responses) is that NGC was the be-all end-all, top dog when it came to coin grading. Apparently the grading standards of PCGS must be quite a bit higher.

I only own one single proof coin in the OGP with COA and I haven't tried to remove it, nor will I but if I suspected it might be a PR70 (Don't have the expertise) and submitted it for grading, would that process involve removing it and possibly devaluing it by its removal? Would I have a lesser valued coin if it didn't meet PR70 standards?

This has been very helpful to me as a newbie. I had actually read an article earlier re the First Strike marketing ploy but what seems puzzling to me is, collectors are aware of it and yet still paying the premium (higher) prices for a coin noted as first strike. Not all collectors, obviously but the dealers seem to have a marketing ploy which is successful for them. Thanks again.
