Need help with these coins 0

[Jules Verne]

Good evening,

My dad has these coins (photos provided) - he asked me to look them up on the internet, can any of you experienced coin collectors tell me anything about them, would really appreciate your comments

 

Many thanks

InWelcome to the Forum.

In the future, it would help us if the photos were cropped and oriented properly.

To answer part of your question, the first coin is a UK 1908 Half Crown and is made of sterling silver. The second is a US buffalo nickel, can't make out the date. The third is European, maybe German.

The third coin looks like a 1913 Prussia 2 Mark. https://en.numista.com/catalogue/pieces13477.html
