These are briefly mentioned in Scott in a sidebar which reads:
Quote:
In 1909 two sets of 16 stamps were prepared for the coronation of Ahmad Shad Qajar. The first set with liion and sun high values and gold borders was for postal use, while the second set with city gate high values and silver borders was inscribed "SERVICE". While neither set was placed in use, both were sold to collectors at a later date.
The stamps are actually highly collectible and bring strong money.
The Persiphila catalogue volume 1 by Mehrdad Sadri (essential for anyone delving into Iranian material) lists them. I only have a 2007 first edition, so the values may be out of date. I need to update my set, but the ebooks for the 4 volumes run about $400. Printed books about double that.
The stamps are valued between US$20 and US$75 per stamp depending on denomination, and are not known reprinted or counterfeited.
I always keep an eye out for them in collections.
EDIT:
Here's a current
ebay auction for 6 of the stamps, at $142 with 9 hours left.
https://www.ebay.com/itm/236616723276Here's a sold listing for 8 of them. The listing says CA$470 (US$343) but since it was a best offer, we don't know the actual selling price.
