Nice coins... The 1937 is a really nice lamination. Are you sure the 1887 nickel is an error? Looks like damage to me. Not a lamination.
Actually, upon second examination, I think you're right . . . I didn't notice the flattening of the obverse rim the first time I looked at the photo(s). Curiously, the coin doesn't seem to have distorted outward at all.
#1 - don't reveal the source of your error purchases. #2 - the V Nickel is damaged IMHO. Have a nice day.
You could get that flattening on the obv rim if it was a pre strike lamination but then I would expect the coin to be light not overweight.
