I belive this big kinda ugly penny is a broadstrike and a double hit?and what causes the black stains on these 1980 pennys?I have several the same year with this same discoloration.

Yes, it is a broadstrike that has been struck twice. As to the stain, it is called environmental damage. As to the exact cause of the stain, it could be any number of things. I suggest a dip in acetone may help this coin to be a bit more eye appealing.

It's a massive broadstrike with a small "indent" (indentation from an overlying planchet). I see no compelling evidence of more than one strike. Expansion varies due to striking pressure and minimum die clearance, which I suspect was quite minimal when this coin was struck. The discoloration and roughening of the surface occured after the strike and is quite unfortunate.Mike Diamond. Error coin writer and researcher.Comment

Your right Mike, looked at it to fast. Is that an indication of the collar on the reverse?

I see no collar scar. In the southeast quadrant one sees a false rim and a beveled edge from transient contact with a collapsing collar.Mike Diamond. Error coin writer and researcher.Comment

it would be ok to dip a 1981in acetone because it is pure copper right?and after 1982 it would NOT be advisable?Comment

That's been my experience. Although I don't know if acetone will have any effect on this kind of crud. It's best on glue, plastic, and resins.Mike Diamond. Error coin writer and researcher.Comment

this is a different coin but see the simular crud?I was wondering if that happened in the mint somehow?by the way I just sold this one ebay for fiftynine dollars and eight cents.I called it one ugly broadsrtike!Comment

The disoloration and the fingerprint on the obverse bear all the hallmarks of poor handling and storage after it emerged from the Mint.Mike Diamond. Error coin writer and researcher.Comment

I was wondering if anybody has tried boilng dirty pennies?I was thinking with deionized water, it might work well on old wheats?Comment

Since most wheat cents that are dirty are in the AG-3 to VF-20 range a mixture of water and baking soda brought to a boil will do the trick to remove most of the dirt and Verdi Gris. A rinse in cold water, then drying the coins immediately should be accomplished post boiling.
This mixture does leave the natural patina behind and seems to do no crucial harm to the coin itself, however, I am sure that many would frown on this practice since it does involve the word "cleaning".
