Hi everyone,
I inherited these two 1899 Russian gold 10 Rouble coins of Nicholas II from family in Northern Norway.
I recently noticed that the portraits look surprisingly different from each other, especially the hair, beard and facial details. One coin looks much sharper and more detailed, while the other has a smoother looking portrait.
I’ve been trying to learn more about possible die or portrait varieties, including the so-called “large head” versions, but I’m still confused.
Mint marks are:
АГ
ФЗ
The coins also have edge lettering and family history connected to Pomor trade between Northern Russia and Northern Norway around the early 1900s.
Do these differences look normal to experienced collectors, or could they represent different portrait varieties/dies?
I’d also be interested in hearing whether either coin appears more collectible or valuable than the other.
Thanks for any opinions or guidance.

Hi everyone,
I inherited these two 1899 Russian gold 10 Rouble coins of Nicholas II from family in Northern Norway (Andenes/Bleik area).
According to family history, the coins came to Norway during the Pomor trade period, when Russian traders and fishermen traveled between the White Sea region and Northern Norway in the late 1800s and early 1900s.
What caught my attention is that the portraits seem noticeably different between the two coins. One appears sharper and more detailed in the hair and beard, while the other has a smoother and slightly different looking portrait.
Mint marks:
АГ
ФЗ
I’m wondering if these differences are:
normal strike variation,
different dies,
or possibly a known portrait variety (“large head” etc.).
Both coins have edge lettering and appear genuine to me.
Any opinions from collectors familiar with Imperial Russian gold would be greatly appreciated.
Thanks!
