1970 Semi-silver Lincoln cent.

"Just yesterday I checked some of the proof cents I have in home. And that one (1970 cent) is the same silver toning you see on some proof of different years."

"It's not a proof planchet."

Carlos, both statements are very likely true. The coloration depends on the thickness of the chemical layer, and to some extent the 'smoothness' of the working die surface. I have seen many non-proof cents with similar coloration, and I believe it is due to the die stage. A new, relatively little used die has smooth field sections which eventually become grainier over time/use. That is why 'proof dies' are only used for a small number of strikes and replaced or used for business strikes in some situations. The first 1000 business strikes from a new die will develop the same coloration as a proof strike IF placed in the same environment.

If it was an old proof planchet it would have had to be sitting around somewhere in the mint for 6 years. And would have to somehow have found a way to make the trip from the third Philadelphia Mint to the fourth one. (Last Philadelphia proofs were at the third mint in 1964. The fourth mint opened in 1969.)

 

the coin in this thread is just a normal old worn out and beat up cent . copper can turn to about any color from being exposed to the elements of nature.

 

Your answer, I liked a lot. The last weekend I found two more Lincoln cents with that particular silver shining reaction. One is 1971 and the other 1983. (both from Philadelphia). Seem like is too much barnish. By the years THE REVERSE is keeping more this stuff, than the Overse. That mean, "I AGREE WITH YOUR STATEMENT"

 

Sorry everybody; but I got to show something else. These two pictures were taken directly under Sun's light. And then I noticed that: the 0 on the date is very similar to the 0 of two 1970 S samples. Can be this 1970 Penny a 1970 S without "S"? Under the date also is a mark like something was broken on the Die.

 

Mr. jookey, there's a "big difference" between PLATING a coin. and SHINING a coin. The Penny in this post belong to the second matter. And give the answer why, some Pennies get Silver toning. And also why some collectors don't like when you clean the surfaces of a coin.

 

if everyone on this forum lied and told you your coin was a rare and valuable one it would still be worth only what it says on the coin " ONE CENT" you sure have a long ways to go to learn about copper coins and the minting process. like I told you earlier this cent coin is just a normal one with normal wear and tear and has been exposed to the elements of nature to change it's color a little. copper can quickly change to any color in the rainbow , the color it becomes is according to what it exposed to.

and no this is not a proof coin without the S

 

San Fran did strike business strikes in '70.
As far as trying to prove a coin was struck at San Fran without a mintmark, it would be like trying to prove the sun isn't coming up tomorrow.

 

True. It's no easy to probe it.

 

HELLO baby! It is wrong that I'm in love? Yeah i know.. about as much as it is sick that I'm drooling I suspect. Don't judge... I don't get out much, LOL!
