Sources & verification

The issue year is the public release year, 1871, not the 21 July 1870 invoice date. The source calls this the twelfth printing; an incidental reference in chapter 3 misnumbers it as the thirteenth. The historical specification places the Crown CC perforation-12½ type on thick white wove paper. It does not distinguish a new thickness by rough versus clean perforation. The 18½ × 22½ mm dimension is the reported historical reference for this halfpenny design, not a certified measurement of the illustrated specimen or a new physical-type distinction. Current date, perforation and watermark identification are retained.
