It is unlikely that there are any fake five pound coins in circulation simply because they are commemorative coins and therefore do not see much circulation, you'd get enough funny looks as it is trying to spend a 5 pound coin. However, there have been reports of people passing off 25p crown sized coins as 5 pound coins. If the coin doesn't say "Five Pounds" on it (and it isn't a gold 5 pound coin!) it has a face value of only 25p.

British general circulation Two Pound coins are made from a nickel-brass alloy.

These coins are not intended for circulation since their value is much greater than Two Pounds.
