This is easier to see if you hold it. Not easy to photograph, but here is doubling on IN GOD WE TRUST on the 1998 P Quarter. There is lettering visible inside the O and inside the D of GOD and there is a secondary lettering to the right and below the R, U, S, T of TRUST and almost all the letters show some doubling although the coin has been circulated a bit. Some pictures show more of it than others, but you can see it if you hold it in you hand.
