The Gibbons catalogue value for a F-65 mint example of this booklet is £35. This translates to $70. The booklet offered here grades F-73 as follows:

Cover freshness: 10/10

The white papers of the panes do exhibit variations under long-wave ultraviolet light, starting with the multiple crown watermark. Generally they vary from low fluorescent to hibrite, as well as various flecked papers.

The perforators used also vary, and the differences lie in whether the vertical perforations extend into the selvage:

• Type I - vertical perforations do not extend into the selvage, so that selvage is fully imperforate at the vertical sides.
• Type I(1/2v) - as above, but one corner of the selvage is skimmed off.
• Type AP - Side perfs extend all the way through the selvage, but the middle row of perforations do not.
• Type P - all perforations extend all the way through the selvage.
