I dug this coin last yr. and am baffled as two why they minted the One Cent piece in two different metals?

That is strange the way it is black all old copper around here comes out green and dont clean well at all.I dug 5 ih pennys and the wont clean at all.You can put olive oil on them and they look good for a while and then back to green.I even rock tumbled them.You are lucky to get them in that shape.

According to everything I have looked up, they only minted them in copper. I can't find a single instance where they were made from any other alloy.
 
The black one looks like it was in fertilizer. I've dug copper coins in that condition from fertilized fields. The line that separates Canada from the date looks different in the photo. Are they the same? The only other thing that comes to mind is perhaps a counterfeit?

Just some guesses,

I would guess that they are both copper, but the copper came from two different places.
 
Dont think its different metal in the coins, they have only been resting in two very different soils.

The left coin has no visible patina and the right one has a patina looking like silver found in saltwater area.

I have several finds like that myself but have not thought about the real clue as to why it happens.Different acidic and alkali soils must be the reason though.

My tip is that the left one is found in sandy good drainage soil and the other one in permanently wet forest ground.
 
It's the same as the clean one. Had me fooled as the other copper coins from Canada around the same year are all copper color like a Wheatie.
 
I found that had a different alloy, Brass, not in the particular time frame of the coins mentioned, I think it was 1853 or so and if you find one of those it is extremely rare and valuable.... HH..Geo
