Adjustment lines or not?

You would expect at least some closure (coming together) of the two edges of the 'groove' where it's squeezed into the deeper features of the die, though, wouldn't you? Being devil's advocate an' all!

Also, with such a wonderful new design and method of producing coins, would they really be up for defacing them in such a way? Again playing DA, wouldn't it be more logical to remove any surplus weight from the edge? It's obviously a teeny-tiny amount if it can be adjusted with a 'scrape'?

The good news is this is easily replicable! We just need to create some grooved blanks and press them into a die to see the affect on the lines. If they remain perfectly straight and complete, I'll concede! ;) 

Gosh, who was it now that was making that penny from his own dies, arctic something I think, he'd have the kit to hand to try it out? Maybe Dave Grunal could try it from a hammered perspective?

Oh, and hi, Colin, hope you're well? :)

Good point....but that assumes they predicted the result

I am doing fine...just keep plodding along!!

Thanks Stu, no apparent 'reduction lines' on your sixpence!
