florin confusion !!

[theshoenlebens]

I'm getting confused
I was looking at purchasing a 1957 british florin. I went too search and some sites say .500 silver and some say Cu\Ni. The coin is in circulated condition so I can't tell by looking at it.
Another thing that is mentioned some as British, Auatralian, figi, what is the difference? I can't really tell by looking at it. Where it was minted has to do with it's content? They ALL look the same to me. I know silver looks much different from others but with the condition, how can I tell? I can't handle the coin so weighing isn't possible either.
Sorry about going on and on but I'm really wanting to get into this hobby and I need to try and figure some of the tricks of the trade.
