Urine is an aqueous solution of greater than 95% water. Other constituents include urea, chloride, sodium, potassium, creatinine and other dissolved ions, and inorganic and organic compounds. Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide. All the chemicals listed above can affect the color of the Cent when it dries. I have seen many examples here in NYC. I am a maintenance worker in a commercial building that has a bar restaurant on the ground floor. When the late night bar patrons and other neighborhood homeless persons decide to urinate at my freight entrance doorway sometimes there are coins that are thrown there. When I sweep them away in the morning they dry up and change into the pretty colors you see on your Cent.
Doesnt smell like urine. For the record thanx to your comment i just rinsed it off wit some dawn to get that dirty urine off...
You actually smelled it? Copper plated zinc are a bad choice for making pennies. Here are some nasty metal detector finds from my collection -
True. Oh I see the difference now... my coin don't look like those are you saying it will eventually? It looks like whomevers urine did a nice paint job on this penny.
