The smallest coin minted in the USA?

Hi,

Not had very much to post over the last few months, a combination of many converging issues. But back to it and this came into my possession today.

A 2 and 1/2 Centesimos or “Panama Pill”

Apparently used to make coins conform to a certain value.

Seems a lot of effort for such a small amount, only 400, 000 minted but the skill is much to be appreciated I think, to have it made so small the dies must have been made by some high expert.
Enjoy

Should have said the measurements are inch increments
