1870

Proof issues:

1870 PR1 Shallow N. (Rev 1868-A)

1870 PR2 Bold N. (Rev. T3-A)

Regular issues:

Organized by reverse type. Errors in the Attribution Guide are corrected here. When I listed the varieties this way (by grouping the varieties by reverse type) errors in sequence and type of matching dies became obvious. This is a very tricky year, so looking at it from different angles helps spot errors and correct them.
