small 1971 2 new pence [решено]

I have this 1971 2 new pence which I came across while bagging my copper jar ready to bank, notice how light it felt in comparison to a standard 2 new pence. I have since measured it against a 1967 half penny and they are the size and weight is almost identical allowing for the 2p's wear. Bearing in mind that 1971 was also the year 2p was 1st released.
Does anyone know of a mint error similar to this or more information as i've search the internet and nothing.
I would be grateful of any useful information on this thanks.
p.s will add images very soon.
cheers tony

The 1971 2 pence was made from Bronze rather than copper. I don't know if this helps but I have no other reasoning behind your difference: I look forward to seeing your pictures.

Found the pics if they work that is, 1st time posting pictues.

I still maintain that it is the fact that the 1971 coin is made from Bronze, although there is an interesting line on your 1971 coin along the side of your coin, a possible alteration of your coin...still I'll probably stand to be corrected. My correction will mean my knowledge will increase.

Well spotted bam777 - could be a 'cut-and-shut'

tony_K_1965 - can you check the alignment?

A "cut and shut"? What is that and why do they do it?

Thanks...I have seen similar lines on a double headed Edward VII coin that a coin dealer that I know has. Also, the Ich Dien on the Prince of Wales coat of arms seems a little faint.

"Cut and shut" is usually done on a car (illegally). Joining two completely different chassis together. In coin terms...(I wonder if radrick could "coin the phrase" (excuse the pun)), joining two coins together...possibly to make you think you have a rare one? An experiment by someone before reintroducing it into circulation.

not quite sure what you mean by alignment radrick007 please advise

Sorry to butt in...but alignment is the way a coin is oriented: medal alignment, when one side is the right way up and if you turn it over the other side (reverse) appears upside down. Coin alignment, when one side is the right way up and if you turn it over the other side (reverse) appears again the right way up. (I hope I have that right). So...your coin, if you turn your coin over is it the right way up, upside down, or is it offset at an unusual angle? That could give us some ideas about your coin.

just remembered, and cut out a hole in some card made markers and its perfectly in line but you can see a line all round the outer edge.

Цитата: @josephjkA "cut and shut"? What is that and why do they do it?

As bam777 so eloquently described, it is when two halves of different coins (or possibly the same coin) are joined together. This method can be used to make a 'double-headed' coin, as mentioned, or to create what appears to be a rare mint error, for example. I can't answer why someone would go to such an effort for such a low-value coin, though, unless it was just a trial piece (practice)

Oh ok, that rings a bell - I've read about magicians using coins with two heads - I guess that's how they are made

Thanks all for the help.
its had my head baffled for while.
