More Pennies

[PWA 1967]

This one, on an F16, has always intrigued me. Ghosting of Victoria's face can be seen (as it often does) above Britannia's left knee, but there is also something strange going on with the border teeth.

The series of pictures at the bottom show an overlay picture of border teeth, from the same coin, which I have made gradually transparent from 0% to 100% as go from left to right hand side. This shows that the marks through Britannia's knees are clearly from border teeth.

I bought this coin at Heritage in 2013 (MS63 Slabbed), and it took me a long time to find another F16 like this, to prove that it must have occurred during the minting process.......rather than the coin being hit with something post-minting.

I will show the pictures of that other coin immediately below, as this picture uses up my 500Kb allowance!!

This is just about the most extreme example I have come across !!!   An 1862 penny

Note the half circle on Victoria's back , its the shield from the reverse side . The extra ribbons are created from the folds in Britannia's. dress 

Thanks ! Interesting coin.

How do you think the edge of the die clashed almost central? Are the two dies not on a fixed axis?

My most extreme die clash .Apologies, not a penny (1696 Halfpenny) .

[Martinminerva]

Spectacular, but not a die clash. This has been completely struck twice and rotated in the dies between striking.

Yes, wrong words used lol. double struck .I'm sure this type is noted in Peck , so not a one off.

It looks to me as if there was nearly a brockage, as the raised detail of the teeth is the incuse detail on the die. If a coin is not properly expelled between strikes, it will act as the die and leave an incuse detailed impression, because a die has the inverted relief, ie incuse is raised an vice versa, so to have raised 'incuse detail', it had to be a wrong-un, because the die would not have changed its relief and would strike normally, albeit off-centre. With several examples known, the detail must have been from a trapped coin.
