1950s Lincoln Wheat Cent-is this Improper Alloy Mix

[Sony572]

Hello, I believe I am supposed to introduce myself on my first post. I am quite new to coin collecting. Several months ago, my husband gave me a box of old pennies that he had collected with his father many years ago. Since then, I became engrossed and have been reading both online and did purchase The Red Book, to gather information and learn what I can.

I do have a collection of Woodies, that I separated from my many Lincolns, but this 1950-s is of a different color and appearance. I am not sure if it is an improper alloy mix or just PMD from some chemical that the cent was exposed to at some point. Any opinions would be greatly appreciated! Thank you for taking the time to view. Sony572

This is not an improper alloy mix. The coin seems to have suffered from environmental damage, or had some chemical spilled on it. It is superficial and not mixed into the alloy at the time of production.

Welcome aboard.

Normally, we would start off with the weight of the coin. A scale can be bought off of Amazon for less than 20 bucks shipped. A scale that measures down to hundredths of a gram is best ( x.xx).

But, this coin appears to have been harshly cleaned. You normally see those tight horizontal lines on coins when the colorful coating, the patina, is stripped off the coin.

Scroll down to the 1956 D coin. This was done just before the post. So it would not have had time circulating to pick up all sorts of debris...

Thank you, both of you, for responding. My husband did buy me a scale, and in the future, I will include the weight of the coins. I will put it in a 2x2 and mark correctly for future reference. Sincerely, Sony572
