It Is Beat Up But I Think It's A 1969 DDO

Machine Doubling :(

It does have some doubling you can see north of the upper curve on the MM.. but it is still Machine Doubling.. the best thing to remember when trying to decide between Machine Doubling and doubled die is the Machine Doubling is flat in appearance.. it looks like a flat shelf off to the side of the design element.. doubled die especially one that is significant as this example would be if it was an actual doubled die would have a rounded hump appearance to the doubled area.. I always had trouble convincing myself when I saw an extreme MD that it was not a true doubled die... now the area I have trouble is the small spread doubled dies where it is very hard to tell if the area is rounded.. then you have to start look for split serifs and such.. I have included another example of extreme MD on a proof dime I found last night in my unopened proof set..so disappointing.. but also notice how the doubling is flat.. hope this is helpful..

Snatched.. have you been to Wexlers website? He does have some very nice photos to help out with this topic.. and reference photos for just about any year and coin you may be looking at..
