I have few Ps and couple of Ds!. not yet certified!. It seems 10c dime minted in Philly seems to be bad quality besides too many errors, doubling etc!. Look out for two eyes, two mouths, eyes are pretty prominent doubling, mouths, second strike (multiple strikes) mouth can be noticed juxtaposed, you can see the corner (small portion) of second one. 2006-P sure is interesting coin..!.
