A little research into the early dollar weights

I was reading Bowers' Encyclopedia the other day and noticed that the issues of 1795 seem to be quite a bit more common than I thought. So I decided to do a little research and see if that was a valid impression or not - and whether the weights are correct in the Set Registry.

First off I went to Coin Facts and recorded the number of surviving examples:

1794 150
1795 FH 10,000
1795 DB 3,900
1796 3,200
1797 3,350
1798 SE 1,350
1798 LE 6,000
1799 8,000
1800 4,500
1801 2,000
1802 2,250
1803 3,000

Translated to a weighting based on overall rarity:
1794 10
1795 FH 1
1795 DB 3
1796 4
1797 4
1798 SE 6
1798 LE 2
1799 1
1800 3
1801 5
1802 5
1803 4

Then I did the same for estimated number of uncirculated examples:

1794 10
1795 FH 65
1795 DB 60
1796 8
1797 10
1798 SE 6
1798 LE 60
1799 125
1800 50
1801 15
1802 70
1803 22

Translated to a weighting based on uncirculated rarity:
1794 6
1795 FH 2
1795 DB 2
1796 7
1797 6
1798 SE 8
1798 LE 2
1799 1
1800 3
1801 5
1802 2
1803 4


Then I tried to factor in 'popularity' by taking into account market value in average uncirculated. I did this because even though there are quite a few 1795 coins [for example], they are extremely popular and held in high regard so this needs to be accounted for in the weightings:

Translated to a weighting based on low unc prices [MS60]:
1794 $660k
1795 FH $60k
1795 DB $50k
1796 $50k
1797 $60k
1798 SE $150k
1798 LE $20k
1799 $20k
1800 $20k
1801 $25k
1802 $25k
1803 $30k


Translated to a weighting based on price and thus popularity and rarity:
1794 10
1795 FH 3
1795 DB 3
1796 3
1797 3
1798 SE 6
1798 LE 1
1799 1
1800 1
1801 1
1802 2
1803 2


And to come up with an overall ranking, I averaged all three weights: overall survivors, unc survivors and unc pricing:

Translated to a weighting based on overall rarity:
1794 10+6+10 = 26/3 = 8.67
1795 FH 1+2+3=6/3 = 2.00
1795 DB 3+2+3=8/3 = 2.67
1796 4+7+3=14/3 = 4.67
1797 4+6+3=13/3 = 4.33
1798 SE 6+8+6= 20/3 = 6.67
1798 LE 2+2+1 = 5/3 = 1.67
1799 1+1+1 = 3/3 = 1.00
1800 3+3+1 = 7/3 = 2.33
1801 5+5+1 = 11/3 = 3.67
1802 5+2+2 = 9/3 = 3.00
1803 4+4+2 = 10/3 = 3.33

Rounding leads us to this:


1794 9
1795 FH 2
1795 DB 3
1796 5
1797 4
1798 SE 7
1798 LE 2
1799 1
1800 2
1801 4
1802 3
1803 3


Thoughts and comments? It seems to me this might be a more accurate weighting than what currently exists

    I often questioned the estimated survival rates in the B&B book.

    Look at it by PCGS population -

    All Grades/ Mint State

    1794 - 90/5
    1795 FH - 2081/35
    1795 DB - 747/29
    1796 - 750/5
    1797 - 795/5
    1798 SE - 301/3
    1798 LE - 2056/35
    1799 - 3298/89
    1800 - 1401/29
    1801 - 480/9
    1802 - 856/35
    1803 - 673/11

    Ok, let's use those and do the same analysis:

    All Grades
    1794 - 90
    1795 FH - 2081
    1795 DB - 747
    1796 - 750

    1799 - 3298
    1800 - 1401
    1801 - 480
    1802 - 856
    1803 - 673

    1794 - 10
    1795 FH - 2

    1799 - 1
    1800 - 3
    1801 - 5
    1802 - 4
    1803 - 4

    1797 - 5
    1798 SE - 3
    1798 LE - 35
    1799 - 89
    1800 - 29
    1801 - 9
    1802 - 35
    1803 - 11

    1794 - 8
    1795 FH - 3
    1795 DB - 3

    1797 - 8

    1798 LE - 3
    1799 - 1
    1800 - 3
    1801 - 6
    1802 - 3
    1803 - 5

    Translated to a weighting based on low unc prices [MS60]:
    1794 $660k
    1795 FH $60k
    1795 DB $50k
    1796 $50k
    1797 $60k
    1798 SE $150k
    1798 LE $20k
    1799 $20k
    1800 $20k
    1801 $25k
    1802 $25k
    1803 $30k


    Translated to a weighting based on price and thus popularity and rarity:
    1794 10
    1795 FH 3
    1795 DB 3
    1796 3
    1797 3
    1798 SE 6
    1798 LE 1
    1799 1
    1800 1
    1801 1
    1802 2
    1803 2


    And to come up with an overall ranking, I averaged all three weights: overall survivors, unc survivors and unc pricing:

    Translated to a weighting based on overall rarity:
    1794 10+8+10 = 28/3 = 9.33
    1795 FH 2+3+3=8/3 = 2.67
    1795 DB 4+3+3=10/3 = 3.33
    1796 4+8+3=15/3 = 5.00
    1797 4+8+3=15/3 = 5.00
    1798 SE 6+10+6= 22/3 = 7.33
    1798 LE 2+3+1 = 6/3 = 2.00
    1799 1+1+1 = 3/3 = 1.00
    1800 3+3+1 = 7/3 = 2.33
    1801 5+6+1 = 12/3 = 4.00
    1802 4+3+2 = 9/3 = 3.00
    1803 4+5+2 = 11/3 = 3.67

    Rounding leads us to this:


    1794 9 vs 9
    1795 FH 3 vs 2
    1795 DB 3 vs 3
    1796 5 vs 5
    1797 5 vs 4
    1798 SE 7 vs 7
    1798 LE 2 vs 2
    1799 1 vs 1
    1800 2 vs 2
    1801 4 vs 4
    1802 3 vs 3
    1803 4 vs 3


    Minor differences using the PCGS figures instead of the estimated numbers, but still significantly different than the current numbers:

    1794 6
    1795 FH 4
    1795 DB 3
    1796 4
    1797 4
    1798 SE 5
    1798 LE 1
    1799 1
    1800 1
    1801 3
    1802 1
    1803 2

    There's just too many '1's in the current weighting scheme and the 1795 FH is overweighted.
