A picture of your screen is useless, way to pixelated.

Spooned coin.

I would assume 4001180-4001199 as these are listed separately in the database on this forum.

Wow!
A rare note indeed.
Definitely do as coinguy suggests, handle it very carefully, do not put it inside a book, and get it certified.
Google BCS grading for certification services.

Your research is wrong.
That page of information is useless.
Your 2000 family quarter is pure nickel and should weigh 5.05 grams.
5.15 is well within normal
Interessting toning.

There have been many minor changes to obverses and reverses during Elizabeth's reign, I can understand why this site only lists the major varieties.

What other years have large single ear ring ?
2008 must have been a watershed year.
It was the last year for that particular reverse as well, 2009 saw the introduction of a new reverse, not just for cents but other denominations as well.

I found pages and albums for PL sets were too heavy, floppy and awkward.
Like coinguy I found a box that was just the right size and am more than happy with it and glad to be rid of the clumsy albums.
BTW for the pre 1961 sets I have a very nice old Wayte-Raymond album, as there are too few for a box.

Yes

Nice!

Neither variety nor error, damaged coin or die.

There were no 1967 proof sets.
They are not proof strikes, they are specimen strikes that PCGS has decided to call proof strikes even though the mint did not have the technology to produce proof coins in 1967.

Great find!
I've been looking for over 30 years without luck.
