If you throw them in a jar of olive oil for 6 months, they will blacken. You will end up with a lot of black disks, and will be just as hard to identify.
Not good. I have failed with cleaning late Roman bronze coins in this way.
Better to passivate the verdigris in a solution of sodium sesquicarbonate in a dish lined with aluminum foil.
Lots of good good Google information on how to make the above solution by mixing baking soda and washing soda.
One of the techniques museums use.
I seriously doubt if the coins are worth anything, but you will learn how recover more valuable bronze coins than these, later on.

@msc, as long as you are learning, you could take a few and follow @roth's advice and take a few others and follow @sel's advice and then compare the results. I'd be interested to see this comparison if you can post it to this thread.

Well crap. What a giant bummer to find. I agree. Experiment away. Maybe split them into three groups and try a couple of different methods.

Appears to be a high percentage of memorial cents--maybe. Experiment away!

Doesn't sound like it's even worth the cost of the alchemy ingredients.

I believe they are cents that make no cents to me.
Has anyone else ever had an experience as saddening?
Please feel free to share yours. Ah! Yes! If you'll allow. I purchased a box of BU LWC's in 2x2 manila envelopes (4 to an envelope) decades ago. knowing that the former owner took great care of his collection, I let them set as is for 40 or more years. When I went to explore, each treasure was wrapped in aluminum foil. Imagine what the electrolytic interaction between the copper ions and the aluminum ions did to the hundreds of coins. The aged aluminum foil, however, was pristine. Kevin |

Looks to be mostly memorial cents. First step is to go through them and see if it's even worth saving any of them. Chance are they are all just common coins worth 1 cent each.
