What do I have??

This is my first post so hopefully I did the attachment right. I belong to the local coin club and they have seen the 1988d and think it was rubbed or chemically altered which after reading other posts I think I agree. The 2001d doesn't look the same or feel the same. They both weigh 2.5 g on my scale unfortunatly it will not go out any further. Let's hear your opinions.
Thanks

Welcome to the forum.

and hard to say with those pictures.

 

so what would help to make the determination

 

okay, I'll go for it.

I presume that you are talking about the apparent lack of copper on the coins.

If so, then look for signs that it may have been removed.

Bubbling, as I remember is one sign.

Other than that, someone else will be along soon to comment.

 

ok thanks... Yes I'm talking about lack of copper color for both and why are they so different. One is very shiney and the other is dull but both have a good strike.

 

I have seen zinc cents that have been heated that look like the second (dull) coin.

 

Try and post larger pics it would be much easier for us to determine what your are saying to us/

my boyfriend has a better scanner I will see if I can use his to get a better image

 

And welcome to Coin Talk!

Chances are high that both are refugees from a middle or high school chem experiment. The following ( or similar) experiment is now in several lab books and are fun and easy for students to do with a "wow" factor.

Copper and zinc are so reactive and post '82 cents have known weight for calculations.

Too long in the solutions can produce the bottom appearance.

Thanks for the link. I'm half temped to put it in fire to see if it turns to gold. The second dull one if it is left in too long would it be thinner and kind of concaved?
