Hi all,
Hopefully the pics will tell the story but here's the background.
Back at Christmas time, I had the opportunity to hunt an old domain. I dug quite a few Brit pennies but one seemed rather different from all the others. Firstly and probably most noticeably, it is quite a bit lighter and thinner than a normal Brit penny. Secondly, it is fractionally smaller in circumference than a normal Brit penny. Also noticable, is that it seems to be made from a different metal...possibly more of a brass/alloy mix.
The first pic is the Britannia of a normal 1919 penny.......the second, is the dubious one, also dated 1919.
Thoughts?
Why bother forging a penny?
All thoughts or idea's welcomed, and thank you in advance.

you should not have washed the smaller one in Coke Cola... it corroded away

But that is the difference, the one is corroded thiner and and the same time the edge is corroded down making the diameter smaller....

Where did you find it? Could be interesting to check the ph of the soil...

I've had a couple like that out of acidic 'swamps'. One was so thin it was almost foil - only ID'd it as a penny by metal composition.
The diameter reduces due to the extra surface area exposed at the edge.

Ok....Firstly, no Cola involved. Secondly, this is a domain that I have lifted probably close to 100 pennies and half pennies out of. All have been a similar depth of between 5 to 8 inches. All, without exception have been in what you would call 'normal' park condition...except this one.
Just seems really odd that this is so corroded compared to all others taken from the same area....some within feet of this one and in exactly the same soil conditions.

The comment about the corrosion affecting the diameter could have some bearing.
However can I see a difference in the bend of Britannia's outstretched arm.
Could be that it is from a different mint than we usually find and so a different die.

There was quite a lot of counterfeit coinage in the late 1800's - early 1900's but it was
usually the silver coins I believe. Papers Past has several references.
