What????

I'm not sure what a " ^$/¥£₩÷" is. LOL.

It's been machined, for some reason, with a lathe or similar piece of equipment.

This is PMD (post-mint damage), and as such makes the coin numismatically worthless, though interesting. It might have been done to make a "magician's coin" or something similar.

There was a similarly machined nickel posted recently, though yours has different toolmarks. I think yours was done on a lathe as well.

Those circular striations are kind of cool looking.

 

I didn't see it at first, but can (barely) see it now.

My only guess would be that it may be some remaining trace of the coin's original reverse lettering? Not sure - can't really make it out in the picture.

 

That one's also been machined, but in a different way. The rim has been squashed down. It got rolled through some piece of machinery.

Some people make rings out of coins and one of the first steps is to flatten down the edges like that. But I don't think that's the case with your cent, there. Cents aren't often used to make rings - people usually go for bigger coins, particularly silver ones, when they're making rings.

I just discovered there is a term for this. It appears to be a "dryer coin", and I found a good illustration of how it happens here.

 

Nope. 'Fraid neither of these are worth anything, except that they got you interested. That's something, anyway, right?

Keep on lookin', and good luck!
