I keep looking at the DDOs from 1974-78 and I cant really see what I'm looking at. They look more like a large date than a DDO to me. I mean what I look at the DDOs from those dates it doesn't add up to me. I personally think the top of the 7 would also be affected with the doubling also. I dont see how just the bottom of the 97 would just be fatter and not effect the top of the numbers at all. I mean when I look at the 1980s DDOs I can see where all the date is affected with the doubling. The bottom of the 9 in the 80s isn't the only thing that shows signs of DDOs. Can anyone explain how they actually got labled a DDO and what actually makes them a DDO.

If you do a search on coppercoins.com for 1974-1978 Philly DDO's they are class 6 doubled dies. The doubling seem to spread toward the rim on the dates. The wide tailed 9 & 7 seem to be the area it affects. Not vertically. Compare a normal coin with these images it will help you to see what is going on with this class.

There are nine classes of hub doubling, each with a different appearance and diagnostics. It is difficult to identify anything other than naked eye doubled dies if you do not understand the individual classifications.
