Question
TYPE A29
TYPE A29  
IS IT POSSIBLE FOR YOU TO HELP ME IDENTIFY THE 'GREEN' STAMP IN THE ATTACHED PHOTO. I CANNOT FIND ANY REFERENCE TO A GREEN COLOR FROM THIS ISSUE DESPITE MANY ATTEMPTS THANK YOU IN ADVANCE

Answer
Hi,
  Great question, and thanks for including the good quality photo with this.  Makes it much easier.  There is a phenomenon in philately known as "changeling".  This occurs in some stamps when exposed to certain conditions, like sulfur.  (If you are collector in a mining town for example, most of your early (1920 and prior) orange stamps will turn brown, due to exposure to sulfur in the air.  There are many types of conditions that can result in color changing (technically "fading" is a type of changeling as well...)
  Your stamp here is a "victim" of such condition.  This is a 78b (gray) variety that has been subject of changeling.  I would rate this VG given it's off centering on 2 sides (left and bottom).  Changeling of this type would take a further hit to book value (about 10% - 20% less).  VG book value of a 78b would be $120, take 10% off, you're looking around book value of $108.
Hope that helps
Best regards,
Scott

Expertise

My expertise is in US, but I have a lot of exposure to worldwide, and with wide reference material, I will do what I can to answer questions about global stamps. In US I have extensive experience in all aspects (does include Administrative overprints for Cuba, China, Puerto Rico etc.). Also, Hawaii general issue and Revenue (pre-statehood). Of course still building knowledge but have been collecting since 1980. Air Mail is a favorite area, but not a limitation. Two specialty areas are Large Banknote issues, and Washington/Franklin identification. Strong experience in Carrier & Locals, Private Die (Also known as M&M for "Match & Medicine" but also includes some playing card and perfume stamp issues.) Recently have been building more back-of-book experience, especially around Official, Newspaper, Revenue and tax editions. Some covers, and cancellations, but not my strong suit. Another area I'm recently diving into. What I can't do: Anything non-US, as it's just not an area I focus on.

Experience

30+ years of learning the hard way. A lot of passion for collecting and dealing (as I do both). I don't consider it a hobby... I consider it a serious pursuit that I'm able to do in the hours I'm not occupied by annoying things like sleep. I work closely with some of the global leaders in the expertizing and identification field. Have co-authored several papers (with Mr. William Weiss Jr.) related to identification, as well as tool set to help with quickly identifying the more challenging areas of Washington Franklin. Strong experience in paper types and coil validation.
