i belive this coins is circulating not non circulating

  I believe this as well. It is only that people collect them as souvenirs that they are not seen in circulation, and I am sure they have not been demonetised, as any coins after 1967 are the current decimal ones.
 Just now also read in a book 'commemorative crown coins (1972 1977 1980 1981) are legal tender for 25p, but they are rarely used by the public, probably because they are too big to be convenient, and to collectors they are usually worth a little more than face value'.
 P.S. To save looking I have checked those other three years, and they do not say non-circulating.

yes and i am sure it should be described as circulating.

Found out that as well. So yes I can, and yes they are. See the link above for what I found.  

thanks - changed

I understand the justification that these decimal crowns, having a trading value of 25 (new) pence, were (are) legal tender and I realise that Tony Clayton describes them as 'circulating' issues - I still struggle with the idea that anyone would have gone, or could still go, into a shop and hand over one of these commemorative pieces as payment for a bag of sweets, for example. The whole idea of these issues were that they were a memento - a reminder of a special, historic event, often bought by parents and grandparents for their offspring as keepsakes. Finally, the one compelling argument I can find in favour of these coins not being 'circulating' is the fact that you would never receive them in your change from a shop, post office, bank, etc. Surely, for a coin to circulate it has to trade both ways, does it not?

I have done a bit more digging. You can draw your own conclusions from the links and quotes below:

http://wiki.answers.com/Q/What_are_the_specifications_of_British_decimal_coins

25 Pence (from 1972 - 1981) 38.61 mm diameter, 2.5 mm thick, weigh 28.28 grams and are made from 75% copper and 25% nickel. The edge is milled. During their period of issue, they were referred to as a Crown due to them being of the same dimensions as the pre-decimal Crown coin. These coins were discontinued from 1982 but remain legal tender. Circulation of these coins is uncommon.

Can I use Commemorative Crowns as ordinary coins? Why are some of them worth more than others?
 
These coins, as the name suggests, are issued to commemorate special occasions of national importance usually, but not exclusively, royal in theme. They are intended to be souvenirs rather than ordinary circulation coins and are consequently seldom found in everyday circulation.

Traditionally crowns had a face value of 25p (or 5 shillings prior to decimalisation in February 1971). In 1990 the face value was increased to £5 to give the coin a value consistent with its weight and size in relation to those of in the then current range of coins.

Each crown issue is authorised by Royal Proclamation in accordance with the requirements laid down by the Coinage Act 1971. This means that - in common with other coins in general circulation - a crown has legal tender status.
 
Most people would not wish to exchange a crown piece, but in recognition of the fact that some people may wish to do so, some post offices have agreed to accept crowns in exchange for goods and services.

Commemorative crowns were still issued with a value of 25 new pence. These were to celebrate the Queen's 25th Wedding Anniversary in 1971, her Silver Jubilee in 1977, the Queen Mother's 80th birthday in 1980 and finally the wedding of Price Charles and Lady Diana Spencer in 1981. Thereafter, all new crowns were given a value of £5, although the first of these did not appear until 1990. None of these coins were intended for circulation but they do have legal tender status.

In summary, my opinion is that, with the exception of some post offices, these commemorative crowns are not being traded for goods and services and therefore should not be referred to as circulating. What do you think?

Those four years I mentioned above now reminds me that in 1977 I actually DID spend some in a shop!
I left school at 16 and got a job in a bank (Midland Bank, before it became HSBC) so by 1977 I had progressed up the ranks to be a cashier. The public had advanced notice when commemorative coins were to be issued, so we kept a list of names and quantities to put aside when we received the bags from the Royal Mint. After we had allocated the list quantity we still got asked for some just by people calling in etc, then as that died down I changed a pound note (before pound coins six years later) into four crowns and spent them round the local shops - and indeed one of them was a sweet shop! So maybe that would not happen these days still, with in this example 1977 25p, but perhaps it could. What about commemorative two pound coins - they do mingle with standard ones.
