1974 Mixed Alloy Penny 1 1

Chemical element Al interacts with Chemical element Cu to tinge the alloy a pinkish reddish hue. 
 

isn’t science cool?

 

notice the rim cud leading into a wire rim?

as well as the profile definition and hair delineation on the well and bold struck Lincoln’s bust.

Wavy die polishing lines behind Lincoln from rim to device.

   Based on the photos, this is a normal, lightly circulated 1974-D cent that was struck from a slightly misaligned obverse die. There is nothing unusual about coins exhibiting die polish marks.  There is no evidence presented that it is of a "mixed alloy" and contains chemical element "Al" (aluminum) or any other element other than the normal copper (95%) and zinc (5%).

Yep, it is. Please let us know when you try some.

Many copper alloys have or acquire "pink" tones, so assuming an aluminum-bronze alloy does not tell us anything.

BTW the obsolete term "wire rim" usually meant a "fin." There is no fin on your cent -- it's just struck a little off center.

The "cud" is missing from the posted photos. Please add one or two.

🐓:  Looks like your fanciful term, "High Wire," for "wire rim," hasn't caught on...

Q.A.:  What can I say?  You win some, you lose some. Now, if you're talking "Speared Eagle," that'll take. That's catchy.
