I picked up this Kennedy yesterday in a coin bin, at a pawn shop, while out buying some silver. I was wondering if any of you would know if this is an improperly annealed planchet or just toning?
Looks like a blow torch or lighter damage Most annealing errors are more uniform across the coin.We also see most annealing errors on clad coins(after 1964).Maybe it 's a create an error/toneing.Whats the slab say?
Here is how they should look I have some rolls some darker then others "Black Beauty" Jefferson Nickel's that are Improperly Annealed.
This is what some sellers say about them.
These Jefferson Nickels minted in 1959, are utterly unique rarities. Reason being - both obverse and reverse are black.
When discovered, they were understandably nicknamed "Black Beauties" in homage to the midnight tones of this one of a kind piece.
The distinctive black finish comes from an improperly handled annealing process. Annealing is the process of heating the planchet to ready it for striking. The planchets are then placed in a large furnace warmed by gas heaters to "relax" the metal. They are then passed through a washing solution to remove tarnish, which gives the planchets (coins) the familiar "BU" (Brilliant Uncirculated) finish.
I have found them not only in 1959's but 58's,1957 as well. I guess it could happen in any date if they cook them to long. You can look at a clear plastic tube and see the darker one's in the tube they stick out like a soar thumb.

Great information Type2, wasn't aware of the 1959 Jefferson "Black Beauties" either. Nice examples!
