Heavily damaged. There's no way at this point to tell if the missing elements were missing as struck or missing as a result of the rest of the damage. Value = $0.10
It looks like there is a trace of the last numeral ( 0 ) still there.... Not sure what you mean by a missing W.... it is a P mint mark... Unless you mean the designers initials...... Anyway, your dime is worn, damaged and environmentally damaged... Worth 10 cents. Cheers, RickO
I might have guessed a little struckthru grease or worn die, but we end up at the same place.
