Now, I do not believe that there could be more than 1 original die. The total mintage was very low. There were a number of instances, however, when the Novodels were produced on Yekaterinburg Mint. There were at least 2 or 3 instances when EM prepared a complete date set of all of its coinage production. (I do not remember the source of this information -- it was an article about Novovdels) Most dies had to be newly made and then destroyed. These instances were orders that were not related to Trade fair of 1870. I am not completely certain that 1830 EM-FX Novodels were produced in 1870 at all. The existence of 1830 EM actually produced for 1870 Fair negates the idea that 1830 em-fx were also produced.
Notwithstanding the above, it is likely that there is a number of different novodels of this series. All those instances took place much later than 1830. It would not be very probable for the novodel to circulate so much. It appears that there is a possibility that we can tell at least one of the novodels from original now.
The source of info you mentioned is Spassky. Exactly this article on novodels says that:
- 1840 official Ministry order to Ekaterinburg for reproduction of complete yearly sets from 1757 to 1840 on new dies. In particular, each year must have incuded all types (even if certain types were not coined at all within a particular year). All dies were supposed to be freshly made for each nominal and for each year. The dies were destroyed afterwards
- 1856 official Ministry order to Ekaterinburg for reproduction of complete yearly sets from 1726 to 1856. In particular, each year must have incuded all types (even if certain types were not coined at all within a particular year). All dies were supposed to be freshly made and be kept afterwards. 1 collection of 1740 coins was made.
- 1870 order for exhibition. The set of 1856 dies was used. It was 4 collections actually and Spassky said that these exact 1856 dies were used for private orders.
When I compared 1833\0 novodel, 1831 original coin, 1833 original coin and your picture I took measurements of ФХ letters (I do not know what is the practical use of that, not a big waste of time though

) so here is a table. Finally I do not really know for certain, but under microscope the shape (not position) of 183X and letters ФХ could be also explained by wear, circulation damage, production defects and not by the engraver's exact design. I do not know how to consider the shape of X, the letter is so tiny so it could just be anything.
