Hello,my friend!
First of all,THE RULES OF THE FORUM say that you should post only 1 coin per topic! Please,keep in mind this!
Not to say I am a bad guy,from what I saw in your coins' photos,I can tell you these:
1) The coins of british kings George V & George VI MAY BE genuine,silver made. But,many millions of them were minted,almost every year,so quite a lot arrived in our days & so they have quite a low collectable value. If you will post 1 coin/topic,I'll be able to provide you more exact catalogue values.
2) With the 3 coins of queen & emperess Victoria, the matter changes:
Only the rupee of 1875 MAY BE genuine & silver made(917/1000)
The other 2 Victoria coins are 100% fakes/counterfeits of FANTASY design!!! 😤😭
