That's a good coin to experiment on.
It's worth about 10c.
How did you clean it?
Coins should never be cleaned. Some will carefully dip them in acetone.
Green stuff was probably verdigris... what was your cleaning trick?
Special acetone?
I use a flathead screwdriver and hammer for the big stuff, then fine grit sandpaper to make it really shine! 😀
*Disclaimer: the above is a joke - never clean coins under any circumstances as it destroys the numismatic value.
It only takes me ONE week to clean mine !
Cleaning a coin will certainly diminish it's value.... In the picture, it appears you avoided scratches or other major signs of cleaning.... I say 'in the picture' because coin photographs can be very deceptive. In hand evaluation would be necessary. Cheers, RickO
Best way is sandblasting. Protective gear is a must. No one will know you had any issues on the coin... well they’ll probably say, “What coin?” After the sandblasting.
Was all that gray stuff cleaned too?
Did you take a "before" picture?
Will someone enlighten me as to why a 1989D cent - cleaned or not - might be worth more than one cent?
Please don't take this the wrong way, but why would you spend so much time on this coin? I would be shocked if it is worth a nickel now.
Please don't take this the wrong way but the answer should be very obvious: It is called educating yourself concerning cleaning coins. We tell folks to start on low value coins FIRST. An image of the coin BEFORE the cleaning would have been helpful.
I too have experimented with common coins that have various types of attached dirt or debris. Distilled water, mineral oil, hydrogen peroxide, acetone, alcohol and others. I have learned much about how debris comes away from metal. I never use a valuable coin. It's actually very interesting. Peace Roy

This methods gets rid of anything on coins and a side benefit is that it also sterilizes them.
What does the after picture look like?
Very good point! With the blurry pictures, I assumed it was another parking lot error thread. Mea culpa.
Its undoubtedly worth $10. It's a well known numismatic fact that each week you soak your 1989-D cent in olive oil that the value increases $5 per week of marinating. Marinate the specimen for a year and it will be worth over $2,500.
So much sarcasm in this thread! No harm, no foul...
Many years ago, My son and I bought a bag of 100 Roman coins for $100, nothing special, but they were mostly terribly encrusted, dirty, etc. Since they were copper, Bronze, etc. I knew they would expand and contract with heat and cold.
We prepared a bath of water on the stove, let them sit in boiling water and then scooped them out, dumped then in ice water. After about 6 - 7, a transformation. In the ice bath, chunks were flaking off. A few more time, it was like a crud storm in the ice.
Taking it up a notch, I, without my son for safety, tried hot olive oil, around 350, below the smoke point, since everyone talks about olive oil, might as well crank up the reactivity. Then it was a dunk in LN2 (liquid nitrogen).
Crack city. Junk falling off everywhere.
Many of the coins had original luster under all the junk, and it was fun /educational trying to figure out what emperor, etc. when they were made, etc.
Some of the coins "died". They were so thin they broke into pieces. There were 5 or 6, I forget, that turned out to be silver in all the mess. A few of the coins actually had some value, and they went back to ebay, and netted a little over $200. But most of the coins were just common, in decent shape, and were given away to friends, used for the Boy Scout Coin Collecting Merit badge, and just plain had a bunch of fun with them.
This thread is useless without before pics of the OP coin.

Seriously..
KUDOS TO THE OP.
Shame on some of the respondents.
Someone is actually trying to educate themselves and doing actual experiments and all some of you can do is throw sarcasm at him.
The slow bath in oil is a common way of curating ancient coins. I once had some fresh dug ancients from Eastern Europe that I marinated for 4 years. LOL.
My question to the OP - is the bubbling of the copper new or was it there before the cleaning experiment? I
A great way to clean coins is to put them inside a hubcap with a bunch of gravel. Then put the hubcap back on the car and drive. The tumbling motion of the gravel will clean up the coin in no time.
We'll use our hands and hearts and if we must we'll use our heads.
I don't get this thread at all. The OP created a thread that announced that they had spent two weeks cleaning and then asked for opinions. There was no indication that this was a practice or learning exercise and no "before" pictures were included to allow people to even speculate that was the purpose.
I, like some other posters, assumed this was yet another cryptic thread about worthless pocket change masquerading as some non-existent error or grade rarity. But, other posters seemed to be sure that this was a scientific experiment being presented for our review.
How about from now on people make clear what the purpose of a thread is when they post it, and not leave people guessing?
To the OP: if this was an experiment in olive oil coin cleaning then I would say "well done", and with more details up front it would be very educational and of a lot of interest to me as I feel I will have the need to use this process at some point.
That's my rant for the day.
@JBK said: "How about from now on people make clear what the purpose of a thread is when they post it, and not leave people guessing?"
You mean like this: "Two weeks of cleaning 1989 d penny. i dip it on virgin olive oil for a week, then dip swabs in distilled water, rub the coin in gently circular motion..."
Perhaps he just wanted to know how he did?
At this point I am reasonably confident that is what he meant, but that clarification only came a day after the original post and after he also posted this: "Is it already worth $10? All comments welcome."
How about something like this:
"Howdie boys and girls, I have been soaking this common cent in olive oil for two weeks to practice removing verdigris from copper. Let me know how successful you think I was. P.S. - sorry I don't have a "before" picture - my dog accidentally deleted it from my cellphone with his clumsy paws."
Why pick on this OP?
His post pretty clearly said he "cleaned" it, how'd he do? I agree that a before picture would have been helpful. But it is not nearly as cryptic as people are suggesting.
And look down the 1st page, people LOVE to post ambiguous titles. I don't know if they are intentionally trying to create click bait or they are just too lazy to be more descriptive, but amost half the threads I open are a mystery until I open them.
You would get better results with sand.
I am not picking on the OP at all (or at least not much) - I am mainly disappointed by the sniping against other posters.
The OP could have been a little clearer up front in regard to why and how they cleaned the coin (did they use steel wool? was it because they thought it was a rare error of some kind?) but that is beside the point. It looks like a successful olive oil treatment now that we know that's what it was.
This sounds like a lot of fun.
Wow, that's the first time I've actually seen one of those 'White hot nuclear' coins I had heard so much about!!! Thanks for posting!!!!!!!
looks pretty good. that green stuff is pesky to remove. i would like better before and after photos because it's hard to tell what else you may have removed or damaged. but based on what you provided, it looks improved.
nice work using a common date coin to practice with.
