I can only assume that this is coated with something. Just checking on others opinions.
Obviously it must have been done quite a while ago because of the color but what do they coat the coin with?
It weighs 3.14 and it is not magnetic.

I'm thinking striped rather than coated, but let's wait for the experts to weigh in.

Either way, it's PMD

Not stripped because the cents before mid 1982 were solid bronze alloy. Afterwards they were zinc core and copper plated. Maybe it is spray paint? A trick to slough off a cent for a dime in change?
My favorite album!

Yes, Rothery, plated. I was just using OPS language.

TNG, I didn't even think about that. Good to know!

All it could be is plating, or real. It's 99% chance plated, but still cool to hold onto just in case!

This is a 1970 bronze cent. Bronze/copper cents weigh in the 3.11 gram range. A steel cent weighs 2.7 grams. This tells it all. Like mentioned before, it is not stripped as there is nothing to strip from this year Lincoln Cent. Plated.... possibly, painted.... possibly, but it is not a steel cent. Still neat looking though.

Just a far-flung thought:

Born in 1948, I spent my youth among fellow street urchins in the projects of the Boston Housing Authority. I remember many times one of us kids held a puddle of mercury in our left palm and by washing them in the puddle, turned pennies into dimes. I've often wondered what one of those would look like today. Of course we under-educated, under-supervised urchins had not a clue how poisonous mercury is!

Given the option of choosing between a very interesting coin or a rather valuable one, I'd choose the former every time . My vexation lies in the fact that the two so often coincide.

It's very possible to Zinc plate a cent with minimal chemistry. Look for a place where the electrode was connected to the copper. Just an alternative idea how these could be made.

Chemistry working for you. When I did black and white photos and the papers actually had Silver in them (film also) I'd drop a penny into the fixer solution and it would collect silver. I don't know where those went if I spent them.

They would be from the 60s.

Good information PPorro on looking for where an electrode could have been placed. Looking at the OP's coin, at about the 9 o'clock position obverse, it looks like possibly a small alligator clip damage where it may have been attached to the coin. Good info to look for on future coins of this type.
