I discovered a CD 143 Canadian Pacific RY. [090] {Slug Plate} in my collection that is not in my 2008 price guide. NOTE: On my insulator there is a period / dot behind the RY. In my price guide there is no dot shown? If anyone else has one like this please let me know. I would also like to hear thoughts on the matter if in fact this IS a new embossing or I'm just not seeing it in the book. Thank you - Les Berkes
