1964-D Washington Quarter "Type C Reverse" REV Of 1965 (Fs-901). Neat Pick.

Well, it's not really a pick when it's attributed, is it? But it's attributed using the old system (FS-024.7), nowadays it's a more recognizable FS-901. Fortunately for me, no one either noticed, or cared, or both, so it sold really cheap.

I have two of these (one ANACS, one SEGS), both coincidentally AU55. It's not a super exciting variety, but looking at the arrow shafts, leaves, and the relation of the leaf tip to the arrowheads (just below the top) in comparison to the other two reverses of 1964 will show you the differences.

Note also the reverse is rotated slightly counterclockwise (CCW) on this example. It's the same way on my SEGS slabbed one, so it's probably on all of them.

There were only two die pairs used to strike this variety!

How exactly the Denver mint got a hold of those two Philadelphia reverse dies intended for the 1965 non-silver coins must be an interesting story, but I haven't researched it.

The somewhat unexciting variety (compared to the famous "Big 5" DDO's in the series) might be tempered by the fact that PCGS still has a total population of less than 200 graded. (I haven't checked NGC.)

In other words there are still probably some of these out there to find among all of the 1964-D quarters you come across in junk silver hauls or searching circulated rolls.
