It's plainly in a grade range where, meaning no disrespect, I wouldn't chance at an accurate guess based on these images. Looks like N-13 (R.1), but even with the Randall Hoard making it fairly "common" in Mint State, it's still a $1000+ coin in MS64BN.
Yes, a very common coin in MS. This coin is very beautiful with blueish green tint cartwheel luster on both side and no ugly carbon spots or green corrosion.
For some definitions of "common." I'm seeing enough in these images to believe it an excellent strike and a lovely coin, but not enough to decide if it's AU58 or MS65. I wouldn't turn it down either way.
The impact of the Randall Hoard on Coronet Large Cent populations for the years it contained cannot be underestimated. It contained coins from 1816-1820, and (estimated from TPG Populations) over a third of it was dated 1820. N-13 is the most "common" 1820 variety - 41 of the last 50 MS64's offered by Heritage have been N-13. At PCGS, the single most common Large Cent of the whole series, in grade, is the 1820 in MS64BN, comprising 20% of all Large Cents in that grade/color, and it's fully a quarter of all Large Cents awarded MS64RB by them (as well as about a third of those in MS65). As Conder mentioned, only N-13 carries an attributed price accessible to lower budgets.
According to Redbook deluxe edition it,s the most common...whatever that means...your coin is a miracle coin...WOW! I would prefer the term"LEAST DIFFICULT"
When I tilt the coin back and forth I can see a nice blueish green tint cartwheel luster on top of the chocolate brown colored surface. There are no dark carbon spots or green corrosion on either side of the coin.
