Many nice coins! You obviously have a passion for the hobby. With a better set up, ie camera, lighting, etc. You should do exponentially better with subs!
greetings from Russia. it's funny, but no one collects coins in slacks below AU50, as a rule, if a coin gets even XF, then the box is broken, and you even have an instance with an F. I'm surprised. and in the video I saw 1 stamp from 1915, I have the same one, only in NGC, in MS66 there are more than 150 pieces, so it's not a rarity, but the coin is very beautiful. good luck and come visit, especially if you are interested in numismatics from Russia.
It really, really depends. Not a one sized fits all situation. To be honest I have seen more people looking to raw coins as of late and it’s heartwarming. A lot of album collectors out of nowhere.
