Gold penny?

[Sleazyj]

Hello all while going through brinks rolls I saw the gold color and thought neat a foreign but when I got to it it was a 2011 shield penny. I put it next to this amazing 1957 D wheat sorry for the quality

i've heard they are a science experiment.

i googled it once to see the chemistry behind it. I'm not a heavy hunter, but I've found a couple.
