The line is ridge ring, it happens on coins struck by a very worn die, very common on US cents, and not desireable.
Your coin also suffers from zinc rot, spend it if you can before it rots away.

Best of luck to you.
Those pics are to out of focus to determine for sure, but I suspect it's large beads because small beads are exactly as described, they're small. You can easily fit another bead between two small beads.
Doesn't appear to be so in those pics.

Deep bag marks, rim ding, piece of ear missing.
MS63 at best.
The Mint shipped coins to the banks in bags in 1952, so what do you mean by original roll?

Neither coin nor token.
A coin is government issued legal tender, a token (usually privately issued) has or had a redeemable value.
Your item appears to be a medallion commemorating 750 years of the city of Wittenberg.

R.S.C. Cap31 will be the same sort of thing.

Wow!
Incredible find, congratulations.

SWL variety
The polishing as noted by coinguy has reduced its value to buliion.
Never ever polish coins.

The OP's obverse pic is not oriented properly, giving the illusion of more rotation than what is actually there.

Slight rotation.
Quite common in '67
Not much of a premium unless the rotation is more than 45 degrees

Couldn't possibly include taxes as those vary according to the buyer's location.

Sounds like the nickel is missing the plating.
That' why the test shows iron and is underweight..
These are easily fabricated and TPGs will no longer grade them.
Value is still 5 cents.

I agree eBay "sold" listings are the most realistic prices.

Which company is grading them as MS62 Red ?

You obviously don't have a copy of CCN Trends.
It's all there.
How do you value your coins without the most basic and popular resources?
Seriously, I'm curious.

Leave it as is

You didn't bother to read what has been posted.
The reference photo is of a '73 coin, the OP's is a '72.
There is no comparison, the reverse design was changed in '73.

It's not a 1972 dollar obverse in their picture, it's a 1973, they made a mistake.
There are quite a few similar mixups on this site
