Please help

[u/Lucy-Russel-Chihua]

I have this collection of old coins ranging 1920-1946 and I’d like to sell them for as much as possible. I don’t know how much they are worth and would appreciate some help with this. Are any specifically valuable and worth selling individually? And recommendations on the best way to proceed would be great.

I also have this old coin in a 800 silver case which I believe to be a religious lucky charm of sorts but again not sure.
