The coin will be larger than the normal planchet size in the case of the cent on a dime planchet. But the Cent die being wider will have some devices fall over the edge of the planchet. The more off centered the planchet, the more one area will be missing devices.
Note at 3:00 the rim shows and at 10:00 the devices fall over the edge of the planchet.
In the case of the 1970-D quarter on dime stock, the metal used to cut the planchets was dime thickness material. Cut into blanks, upset into planchets and struck. This is a know error as there are several of these known. The quarters will have the reeding on the edge of the coins, like normal, but just the thickness of a dime. So if you had received a OBW roll there would have been more than 40 quarters in that roll. (Not all would have been that way) So the thickness is different not the outside diameter.
