British Crowns [gelöst]

Is there anyone out who wants to swap these I started to document a few I have but have ended up with a fairly large pile!

I would have more love to them but honestly can't tell if there copper nickel or silver ones

all you need to do is look up the dates as usually what date they are minted will tell you whether they are silver or not silver

Sorry but thank you for the help.

I actually mean the new 25p coins but I just can't win with them and I am actually so perplexed I would swap them on the basis they were all copper nickel.

I just can't win, I would do an ice test but I just can find a good reference

The coins are the Churchill, silver jubilee and other

Any help

There Cupro Nickle and worth 25p each unless there BUNC they did mint some in Silver but you can see the difference.

Caught my attention how do you spot the difference?
that is the answer am looking for please
