1972 D Washington Quarter, Filled Mint Mark?

[FLtreasure]

Would this be considered a "filled in" mint mark? Most of the same year/mint quarters have a normal D mark that I've found online. There were also a few that had the same type of D marked as the quarter in the photos I posted. Thanks for the help guys!

If the mint mark was filled it would actually disappear. Your coin is that way because the center post broke out of mint mark on the die creating a void that filled in with metal.
