88P Roosevelt Dime- What is that below the middle acorn?

A die chip/chips or die clash from the obverse or something else???

Here are some pics including 2 Normal Reverses on another 88P dime for comparison.


Thanks for any help!

Here is a picture of the Obverse from the coin in question.

I'm not exactly sure. Your close-ups are too blurred for me to make a secure diagnosis. Examination under a microscope would be necessary. Since the blemish seems incuse (or mostly incuse), and since it seems to invade the lower border of the acorn, my hunch is that it is post-strike damage.

Thanks Mike.

My friend has a scope.

What should I look for as a tell-tale sign that this is post mint versus mint error under the scope?

Thanks,

Chuck.

If the defect(s) are incuse, look for the presence of pressure ridges alongside. Metal is generally pushed up along the side when a coin is gouged or dented.
