I am always happy to enlarge my postage dues collection. There are so many varieties of shades, watermarks and perforations that collecting them is a constant challenge. I still have the problem with not having the ACSC catalogue and so I have to call for help one more time. I recently purchased a one penny stamp perforated 14 with the crown double A watermark. The shade of this stamp is very close to the one of the perforated 11 stamps on thin paper, making it very different from the usual perforated 14 stamps. Is this stamp rarer and then what would be it's SG and ACSC catalogue numbers ?
Thank you again for your help,
