Is This 1797 Large Cent The Ultra-Rare S-121A Variety?

I'm new here and this is my first post, so bear with me. I would like an opinion on this coin.

Yesterday, I bought a lot of 3 large cents, dated 1797, 1798, and 1800, at an auction at my coin club for $15. The 1797 was in FA-02 condition, the 1798 was AG-03, and the 1800 was AG details with a hole. I sold my dad the 1798 for $5 (which we later determined to be an S-184 valued at about $50 or so). I got an offer of $15 for the 1800 after the auction, but I declined thinking it had a rare overdate (not the case, but it was the S-197 variety that had a die chip in the first 0, giving the illusion of an overdate.). Then, this morning, I decided to research the 1797's variety. The first diagnostic was the reverse of 1796, so I went from there. Then I looked at the date, which had the numbers close together and evenly spaced. The last diagnostic was the edge, which was plain and had no gripping (which is somewhat like reeding). All told, I figured out that this was the S-121a variety. When I tried to research price, there was nothing to compare it to, save one example here: http://larrybriggsrarecoins.com/ind...duct_id=1182 . It is comparable to my coin's condition. This variety has a rarity rating of R7-, meaning fewer than 20 are known to exist! With the highest grade being a VG-10. I still need it to be checked out, but I think this may be a $2000 coin! Needless to say, I'm stoked!!

I'm trying to prove that it is not the 121a, but I'm not having any success in doing so. As of right now, I am 95% sure this is the real deal. I just hope this doesn't turn into a disappointment...

Here's my coin:











If you look closely to the left side of the obverse, you might be able to see a more worn/ raised area. This was a huge die break that is a diagnostic for the die pair. It is rather obvious on the coin in hand, but you could compare it to the coin in the NGC link above.

Here is a reverse of 1796 (1795) (the rare one):



Here is a reverse of 1797:



Here is an obverse of a 121a:



Here is an obverse of a 120a:



And here is an example of a "gripped" edge, which is the more common variety:



The edge of my coin is completely smooth, except for rim bumps, which is the rare variety.

Thanks for you time for looking and evaluating! Your help is greatly appreciated!
