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.//
