General guidlines - members can post pictures of Overton varieties for the year, or other pertinent information. Questions for 1820 CBH's are welcome, along with attribution advice. Keep picture size reasonable.
Ultimately, an image of each die marriage for the year is the goal. The rest of the series can be found Here
Thanks to Mozin for starting this great series of informative numismatic threads!
The year 1820 had the third lowest mintage of the CBH series with 751,122 coins and 8 different Overton die marriages. This year also has two 1820/19 overdates, both of them very visible without a loupe. Some believe 1820 O.101 is actually an 1820/18 or 1820/19/18. The O.108 variety has a doubled die reverse, which is from hub doubling and not machine doubling.
The 1820's are Sub-Design Type #4, which covers the years 1817-1825. When John Reich resigned in 1817, Robert Scot created a new obverse master die and master hub. Scot lowered the relief and modified the hair details, probably to obtain better metal flow and die longevity, as the aging Scot was now on his own to engrave the dies.
Here is my favorite overdate of the series, 1820/19 O.102, which has a rather flat obverse strike from heavy lapping:

Thanks for starting this 1820 CBH thread.
Some diagnostics for Small Square Based 2 1820/19 O-101 R2:
Obverse: Star 1 points to lower half of dentil. “20” cut over “19”, and maybe over “18”.
Reverse: “S” in “STATES” is sharply lower than “E”. “5” has a short curved top, and a large round loop. Some specimens show a die lump in the upper angle of “N”. “I” is centered below “T”.
Some diagnostics for Small date Curled Base 2 1820 O-103a R2:
Obverse: Star 1 points to upper half of dentil. Late die state shows a crack from edge near star 11 down along edge of curl, to top of “1“, and to edge.
Reverse: “D” in “UNITED” is lower than ”E”. This specimen shows a rotated reverse. “I” is centered under left side of “T”.
Some characteristics of this die marriage are:
Obv-Star 5 is recut on two inside points, star 7 nearly touches the milling. It has a square base no knob 2
Rev-Right sides of T and I nearly in line. The lower leaves show recutting and there is a sharp center dot
It's what caused me to find and purchase on Overton 3rd Edition.
Now I gotta go find some unattributed Bust Halves ...

O-101 and O-105
Some diagnostics for Small Curl Based 2 1820/19 O-102 R1:
Obverse: Star 1 points to lower edge of dentil.
Reverse: “A’s” have defective right serifs. “I” is centered under left side of “T”.
Some diagnostics for Large Date Knobbed Square Base 2 1820 O-105 R1:
Obverse: Star 1 points to upper half of dentil. Date is widest of the year. Star 2 is recut with two extra upper right points. (Obverse shared with O-104).
Reverse: Triple dentil below leftmost leaf. "5" is tipped sharply right. Left side of "I" under right side of "T".
A close up of the small lumps in the field below the "I" in United
Another close up of the "ME" joined at the top
Some diagnostics for Large Date Square Base Curl Top 2 1820 O-106 R1:
Obverse: Star 1 points to upper half of dentil. Date is very narrow. (Obverse shared with O-107.)
Reverse: A die line joins “M” and “E” at top. Small lumps in field below “NI”. “I” centered under left side of “T”. (Reverse shared with 1821 O-102.)
This is the first use of obverse die 4 which was later used on O-105. Star 2 is recut with two extra upper points. The widest date of the 1820's. Open top knobbed 2 with a square base.
The second use of reverse die C, now called C-s2. This was first used on O-103. On the O-104 the die cracked in two distinct locations. The first through 50 C across the lower arrowpoint to the edge. The second through RI toward the tip of the right wing.
For me, this is the easiest 1820 to attribute.
Somebody forgot to put the left serifs on all of the E's in the legend.

A beautiful problem-free Bustie.
Thank you for the post.

I thought some of you would like to see pictures of the die cracks in the obverse die as it broke up while striking the LDS of this die marriage.
I will post pictures of both my EDS and LDS of the O-105 die marriage. The EDS is rated common or R1. The LDS is R3 for scarce.
The obverse of this die marriage was struck with Obverse die 4. This was the second and last use of this die. It was used immediately prior to strike the very scarce O-104.
The reverse of this die marriage was struck with Reverse die D. This was the only use of this die.
This is one of the EASIEST 1820's to attribute:
It is the only 1820 die marriage with a triple dentil segment by the left leaves.
Photos of the 1820 O-105, R1:
*************
Obverse die 4 broke up during the striking of the Late Die State of this die marriage.
Not just one break, but FOUR long die breaks.
It is a little tough to see the extent of the cracks in the coin I have pictured. I have marked them with those little red arrows again.

Some diagnostics for Small Square Based 2 1820/19 O-101a R3:
Obverse: Star 1 points to lower half of dentil. “20” cut over “19”, and maybe over “18”. On this LDS, the thin line showing at the bottom loop of “9” inside “0” is disappearing.
Reverse: “S” in “STATES” is sharply lower than “E”. “5” has a short curved top, and a large round loop. Some specimens show a die lump in the upper angle of “N”. “I” is centered below “T”.
Your coin is obviously defective, send it to me.
When FEVER sees your post, I am sure he will know better.

Have you ever wondered what a Capped Bust half dollar looks like after sitting for 40 years in a old leather pocket purse, with several other old coins? Here you go!

Too bad so many pictures are now missing from the earlier BiddlesBank thread.
1820 O-103 R1
This utilizes Obverse 3 and Reverse C
Obv- This is a small, curled base, curled top 2 and a large 0, the date is low with the stars large and clear of milling.
Rev- Most early state examples show the second T in STATES has been punched over a low first punch, This reverse shows narrow A'a with small serifs at the base, the base of the D is much lower than the base of the E
I wanted to show my Early Die State example of this coin.
The O/P book states: "Some, but not all specimens, show a die lump in angle of N. A fine die crack from edge across lower pair of olive leaves to claw is evident on some specimens."
My EDS of this coin does not have the die lump in the N nor does it have the die crack.

Great BST purchases completed with commoncents123, p8nt, blu62vette and Stuart. Great coin swaps completed with rah1959, eyoung429 and Zug. Top-notch consignment experience with Russ.
Your Bustie looks to be O-103 R1.
Here's some 1820's on these pages:
You just don't see them this nice!
I bet in the grades you have, one would need to search high and low to match them.

Some diagnostics for Large Date Square Base Curl Top 2 1820 O-108 R2:
Obverse: Star 1 points between dentils. 2 is tipped to the left, unlike the two previous marriages. Star 5 is recut on two lower inside points. Star 7 points to upper half of dentil, upper edge of headband, and nearly touches dentils.
Reverse: Lower leaves are recut. Sharp centering dot between crossbars 4 & 5 at left. Right sides of I and T are in line.

The first is my dirtiest bust half. I like to think it's 19th century grime. O.103a, R2.
The second is an O.108 R2 from the collection of Roger Solomon and a class IV doubled die, true hub doubling on the reverse (left wing, talons, claws, leaves, berries and arrow heads). The pictures don't do it justice.
