What's the reference book for European jetons? I don't know if there's one, I'm interested in Monte Carlo and Italian old jetons.
I've seen the pdf version of Thomas C. Day appearing on the club magazine, interesting for id, but where can I find some value?

What could be the value of this old Montecarlo jetons?

the 20 seems to be 5g, the 50 is 7a, the darker 100 is 8h the other 8f over the guide.
