1837

USA: The US Gold Coinage standard changed in 1837.






The Gold Par, stated here:
(Au) $ 1. = 
(Au) $ 1. = Fr. 
(Au) $ 1. = Preuss.Thlr. 1.2356






Huge Discrepancies in Value of Austrian Rix-Dollar : $ 0.7777 - $ 0.95758 ; most assume the higher rate.

Austrian Coin, at US Mint (1841): Fl. C.M. 1. = $ 0.488:
Jan-Dec37 $ 0.4922 - 0.5550; Average $ 0.5141

Where Fine Silver by British assay of actual coin was 176.85 Grains Troy, = $ 0.4763 
Jan-Dec37 $ 0.4804 - 0.5417; Average $ 0.5018

Nov. 1837
 



Dec. 1837









Circa 1838: Where 1 Rbl (Ag) weighed 20.7356 g (.875 Fine) = 18.1437 g Fine Ag,
c.1832-7: 1 Rbl.= $ 0.7542 (Ag) ; ∴ $ 1. (Ag) = Rbl. 1.3259

Consequently, at the Silver Rouble Rate, if follows 3 Rbl.= $ 2.2626 (Ag) ∴

1837:  1 Ozt. Platinum (SPb: Coined Pt)= (US Ag) $ 6.8092




Circa 1823-37? Where 1 Preuss. Thlr. (Ag) weighed 22.226 g (.750 Fine) = 16.67 g Fine Ag,
c.1832-7: 1 Preuss. Thlr.= $ 0.6929 (Ag) ; ∴ $ 1. (Ag) = Thlr. 1.4431

Citation: A Manual of Gold and Silver Coins of All Nations, Struck Within the Past Century, Jacob Reese Eckfeldt (1842) p.106


By the Mint Standard until 1837 (see above), $ 1. (Ag) = Thlr. 1.44



(Rudolstadt in Thuringia) Germany:

Where 1 руб (Ag) = Preuss. Thlr.(Ag) 1.076923, so theoretically it follows that
3 руб (Ag) = Thlr.(Ag) 3.2308, assumed 10.35 gr (but 215.740 Holl.Ases = 10.3687) ∴

1837:  1 Ozt. Platinum (SPb: Coined)= Pr.Thlr. (Ag) 9.6914  {Thlr. 9.70}
($ 6.748; $ 6.7155, $ 6.6839)


However, where the 3 руб Pt. coin weighed* 0.332574429 Ozt (10.344221 g.) and valued  Preuss.Thlr. (Au) 2.786453, ∴

1837:  1 Ozt. Platinum (SPb: Coined)= Preuss. Thlr. (Au) 8.3784 ($ 6.78)

It should be noted the reported weights differ; I've employed 159.776 Grains (~10.353 Grams) consistently. This table appears erroneous, or dated (c.1821?)
