Below are links to images of so called dollars that are not listed in Hibler and Kappen's book. These are all from my own collection. For me, finding new unlisted pieces has always been one of the more enjoyable aspects of so called dollar collecting. As you might guess though, rarer pieces are becoming harder and harder to come by. All of the pieces listed here are prior to January 1st 1960, are unholed and unlooped, and show no signs of loops having been removed. Next to each piece I have included a small amount of information, including diameters and my best guess as to rarity. I am generally more uncertain of rarities of unlisted pieces than I am with listed ones, but I gave it my best shot. I used the same descriptions as used in HK(common, scarce, very scarce, rare, very rare, extremely rare). Note that there are no "off metal" pieces included in these groups. Included pieces are as follows:
both sides exist in HK but on different HK numbers (the reverse of HK42 combined with the reverse of HK46 for example).
one side exists in HK, but the other side does not.
neither side of the piece exists anywhere in HK.
Also, all pieces pretty much follow HKs guidelines, at least as far as my interpretation of the book goes. I am not suggesting that everyone else should necessarily follow my guidelines or agree with them. These are simply the guidelines that I have generally used over the years to help maintain my sanity. I have also collected a few pieces that are probably borderline or outside of HK's guidelines, and maybe I'll put up images of these later.
So called dollars can be grouped in a number of different ways. The groups that I came up with seemed to work well for me with what I had. Some of the pieces could just as easily have been placed in one group as another, so in some cases my decisions as to where to place pieces was somewhat arbitrary. All pieces are numbered for easy reference, and I am sure this numbering scheme will be only temporary.
