Found this in pocket change 

57 is fatter than most normal 

is it worth sending for grading 

My error 

I figured all 1999’s might have a wide AM error 

PCGS

1999 D is this a wide AM ?

Is the lower dark 1998 penny a wide AM?

Are all 1942 nickels silver and How do you tell the difference between nickel and silver, other than the P,D or S above the dome?  I have a 1942 nickel without any mint marks and it has that gray patina that resembles silver 

I found this 1987 penny that has a raised circular (cud?) would it be something to have graded and error checked? Is it worth anything?

it also has telltale marks on the reverse,  of columns outside the memorial on an angle. The 2 images were to large so I couldn’t post it 

Any help would be appreciated 

Thanks 

Does weight matter, 3.0 gms?

What does it cost to grade a coin like this
