The Old "Black Beauty" Question Again

Here's something I found on the net. I have the same problem and still don't get it.

I am almost positive this is not a Black Beauty . I believe it's just environmental damage .

I don't think it's a Black Beauty.

I am not sure but maybe an XRF tester? I wonder how the TPG's test for them.

From what I understand there are at least three criteria that have to be met for the Black Beauty designation.

1. Consistent dark grey color over the entire coin surface including the rim.

2. The original mint luster must be intact.

3. The year. While there are a handful of examples from a few other years and in theory this could happen in any year, the average collector is only going to find them from 1958 and 1959. Also I think this only happened at the Philadelphia mint.

Do some online studying, look at some pictures. If you can find a certified one that you can see in person. Once you see it you will never mistake environmental damage for what these beauties are.

Remember that the coin was improperly annealed before it was struck and it turned dark after it was struck. Most of the coins I see on this forum are examples of the coin being improperly annealed after it was struck, i.e. heated with a torch or heated in an oven. People will do this in hopes of getting some wild toning effects. Check ebay for toned Jefferson nickels and you will find some wildly toned coins, these were heated to get the effect.

Oijogja....while I pretty much agree with what has been said, I truly believe that there is something going on with some of the more modern nickels. I have an entire coin tube filled with "brown" nickels. The ones most interesting to me are five or six that would be grade as UNC, but they look like they have been powder coated. All of these from over a year of collecting and thousands of nickels searched. I did luck out and find a 1959-D Black Beauty, but mine is more brown than black. There was a guy on the forum from Canada that was going to try to figure out why some turn brown. His research was from a scientific standpoint, but he emailed me several weeks ago and said he suspended his study because it destroys the coin.

I've heard that if you take an older composition nickel, meaning pre-1964. heat it in a vise until red hot and immediately into COLD water this will change the metallic properties to simulate improper annealing, be interesting to grab a few 64's and destroy a few trying...gee, need a torch, think all my O2 bottles by my vise will be safe...
