Two new variety pickups - 1936 Mercury Dime DDO and 1952 D Washington Quarter (Medium D?)

Picked these up this weekend - interested to hear some opinions on these:

1936 Mercury Dime DDO





Not sure which one this is, can't seem to match it up to die markers over on Wexler's site...

1952 D Washington Quarter "Medium D"

Now, this MM is definitely bigger than my other UNC 1952 D MM, but it's the wrong shape for the "Huge D." With the damage, I think it goes into the melt pile.
