Well the mirrored trust is a little raised. my ? now is what happend to the letters in america the ERI are gone but the M is still there, and you can see the S in trust over it.
If the reversed TRUS appears slightly raised it must be either an optical illusion or evidence that it is a faked error. What could create raised reversed letters? There is no way to create such a thing from a piece of a coin, piece of a die, or even a piece of a hub. You would have to have something with forward INCUSED letters. As for why the ERI is not vsible but the M is, the ERI are at the center of the impact area where the pressure was greatest and they got flattened, The M and the C are at the edges where the pressure was lower and they survived.
That makes sense because that would be fromthe reverse being "embossed" and that section was driven into the the other coin. you coin is dented in on the obverse and has a corresponding raised area on the reverse.
