Struck fragment

[Maxorin]

Heres a picture of something you dont see every day on old coins.
Nothing spectacular, but fun to find

Theres a fragment on the 9 in 1967, still bearly attached to the coin.
Its possible to flick it gently up and down, and under there is a faint 9.

Had if fallen of, it could have ended up being struck on a planchet,
but here it is, 40 years later. Actually found it in a 10lbs bag of
mixed coins, just laying there scraping against the others.

forgot the picture in the previous thread of course

I'd say it's more likely to be a lamination error.

[Maxorin]

Yes you are right, its a lamination error, just thought it might be an example on how a small piece can get struck, then fall off and maybe get between the dies. But maybe it wouldnt have made any difference, since its so small.
Not important anyway.

Looks like a Retained Struck Fragment, however a Mike as commented it is more likely to be called a Lamination. With a lamination we should be able to see an area of disintegration under the fragment. In this case we have a very normal looking area under the fragment.

A lamination error is intrinsic to the planchet. A struck-in fragment (a.k.a, retained strike-thru) comes from outside. There are situations in which it's difficult to tell them apart, especially when they've almost peeled up completely. When firmly embedded in a coin, a struck-in fragment shows a narrow fissure around the edge. A lamination flake will show no such fissure.
