I forgot to even check it for a "B" reverse. But it is not one
after checking it. I think the reason it may look like one
in the pictures is that the "T,A,T,E,S" in States looks to have
had grease in the die when it was struck.
I do need to get a lot more familiar with these. I guess between my lack of good familiarity, the weak strike and unfortunate camera abngle I just got thrown.
Incidentally the '72-D was the last date minted before 1979 to disappear (statistically) from circulation in AU condition. This occurred about 1996. It very soon after disappeared in XF as well. A few XF's that were saved since the states issues were released have trickled back into circulation.
I suspect it held up so well because the surfaces were harder but there may be other factors as well. An AU is a pretty tough coin today but was common as recently as the late-'80's.
Time don't fly, it bounds and leaps.
