Cannot help you with the I.D., but I am willing to bet an embarrassingly small minority of collectors can name each of those elements.  One wonders why, if Iron comprises so little of the coin's composition, anyone would bother to even include it.  (Maybe this hybrid alloy could be used to mint new cents, more economically.) Nice piece!

How so?  I see 11 hrs., 11 hrs., 10 hrs., and 10 hrs., followed by my own now... unless you mean this matter had been addressed before with less than a satisfactory response.  🤔

Strange. Mine originally had a 2018 date. Now it's normal and currently says 17 hrs ago.

The alloy is more-or-less typical raw copper. 18% lead is a little high. It might be one of the Latin "aurichalcum"-type of golden colored alloys used for Roman sestertius and dupondius denominations, but the absence of zinc is puzzling but the tin might compensate in producing the "golden" color; as is the absence of trace elements such as silver, arsenic and bismuth.
