BLACK LINE ON COINS

Have a few coins with this same black discoloration. All were in sealed envelopes with no seam to allow contamination in a straight line like that. What causes this? Thank you!

Its corrosion, I would bet that before the coin was cleaned the entire surface was very dark to almost black, The cleaning/dipping took the worst off but that area is etched into the coin and is more stubborn to remove. The etching itself may have been caused by a rubber band.

Never a slave to one plastic brand will I ever be.
Could be the sealing chemical....You cannot have a sealed envelope without a seam....Cheers, RickO
The holder had a rubber band around it. Rubber bands are very high in sulfur. Stretch one a few times and smell it. Many years ago a fellow coin club member had a brilliant proof Trade dollar that he stored in a small cardboard box lined with cotton. He stored it for several years with a rubber band holding the box lid on. There was a dark black line crossing the surface of his coin. This is why I always keep rubber bands away from my coins.

Coins were never cleaned. Stored in glassine envelopes for decades. No glue on envelopes. Should have been more specific😁 Thanks!
I do not have one rubber band in my house. Danger.
He who knows he has enough is rich.
I am a skydiver, I have hundreds of rubber bands at home at all times😁😁😁
May have had rubber bands on them at some point in the past.
👍👍👍👍👍👍
Rubber band is my first thought.
Ditto rubber band damage.
I fly a 182 for skydivers occasionally in Kentucky!
looks like rubber band damage to me as well
As you should😁😁😁
Usually jump from Twin Otters and Caravans, but jump at a DZ in Lexington, Texas that flies two 182s🪂🪂🪂
?? I am not expert but that coin looks heavily cleaned to me. Maybe not by you, but by someone else....
Unless you were born a lot earlier than I’d guess and have had possession of the coin since 1878😉, you can’t know that. It looks to have been cleaned.

Rubber band for sure
My guess: Rubber band.

Of course it could have been cleaned. Would have likely been done before 1930 if so. Not arguing.
If it is a rubber band, it's the kiss of death!
It will always come back!

Wonder if they had a roadie who collected coins..............
I had no idea rubber bands had a high sulfur content. I always use a rubber band or two to secure five or more flips with coins in them. That way they're not scattered all over my desk. I suppose I should reconsider this practice.
Bad idea! I've been there, done that and it didn't end well!
Nice pics!
