Here's two pictures on PCGS Coinfacts side by side (both are MS65). See several differences , most noticeable on the numeral 5.
Any explanation?

Yup on the five as well as the one. Did the different fives appear on any other denomination in that year? Peace Roy

Different dies, don't worry about it.
Maybe 2 different hubs were used in 1846. The 5 appears to be from the same punch, just rotated. Were you able to compare it to 1845 and 1847 coins?
Are these die varieties cataloged?
Maybe @IVB can shed some light on them. Peace Roy

I have both the Bitkin and Conros catalogs and there is no mention of these die varieties.
However, these varieties are common.
An interesting fact is that it was during this period (mid-1840s) that the re-equipment of the St. Petersburg mint was made. The outdated Boulton machines were replaced by new machines designed by Uhlhorn and Tonnelier.
