I am way outside my interest area with this, but a co-worker asked me to look at the coins he inherited when his father passed away; and it was all pretty much what you would expect. But one of the 2x2s was labeled "Flat 7" and I find nothing at all on that in the Red Book, which is as deep as I can go with something like this. Internet Searches turn up nothing. It is a 1937-D Walking Liberty Half (typical VF/XF). Does anyone have any other information on the variety? Thanks! Mike M.
