Maybe this will help you. I flipped yours around correctly (like you should have) and have it with the image from Wexler's. Look how thin the top of the TR on yours is compared to Wexler's. There has never been a normal crossbar of the T that thin on a Washington quarter. That, by definition, makes it MD.
Actually I believe those are just regular good old fashion business strike 1967 Quarters . ( Correction . I meant Jay420 ) ... But hey what do I know I'm still just a rookie trying to earn stripes . Lol
