MDD on letters and mint mark. Larry Nienaber
Your half dollar is not the 73D DDO-001 (FS-50-1973D-101)...see attached photo. I don’t think it matches anything in the CONECA Listing. The 73D...
When you en-large the photo of the date it looks like there may be some doubling, not MDD, on the 6 and the 9...note the notching. Larry Nienaber
What you are seeing is Series Doubling on your 71D (SDO-001), which is found on the ODV-003 (Obverse Die Variety). You can read the description...
MDD (Machine Damaged Doubling)...I think using MDD is more appropriate, using the words Damaged Doubling tells a lot! Larry Nienaber
At some point some of the clash marks may have been polished from the die. Larry Nienaber
I agree with the other posts...the doubling on the profile of your half dollar looks like MDD (Machine Damaged Doubling), very common on 90’s BS...

Not a doubled die. Larry Nienaber
I would give you the first two as RPM’s...but they are very minor. Larry Nienaber
I would say none of them are RPM's...just MDD. Larry Nienaber
You must be from New York...NY
It looks like a LDS RPM to me. Check out the markers for the southwest and west RPM's in the CONECA listings and see if you can find a match....
The area looks raised to me, which would mean it is recessed in the die. You can also see polishing lines...maybe it was hit with a small...
It might be from polishing on the die. Larry Nienaber
Sure a doubled die can become damaged during the striking process. Here is an example, a 69D DDR-009 Kennedy Half Dollar...note the MDD near the...
You guys should be able to clearly see the MDD on the last L and O of MONTICELLO, and the N and S of CENTS, for the reverse in his last photo....
Using Abbreviations on the Forum: I have noticed that there are so many abbreviations being used on this forum in regards to Varieties. I...
