As has been discussed recently,
ebay seller boots4222 offers some egregious fakes. However, amongst the bogus there are also genuine items and occasionally ones that are worth pursuing. I mentioned an extremely attractive R132 with a cert, that garnered real money at $2,640 vs. a catalog value of $3,500. Barring unrevealed faults, a very nice stamp... but beyond my pay grade.
About a week ago, an astute user of my website alerted me that an example of Scott #R15e (2c USIR on green paper) that I had listed in my census was on
ebay if I was looking for a better image than what I already had. I thanked him and figured while I was at it I would set a lowball snipe, not expecting to win.
For some reason I won it, and despite the stamp being flawed, IMO it's a heck of a deal just given the scarcity of the stamp. In my opinion, even with the defective corner it's worth at least 20-25% of Scott given that it is sound otherwise and has a cert. It's a truly scarce stamp.
I've now owned 4 examples of R15e: two purchased with certs and two that I found in collections and subsequently gotten clean Philatelic Foundation certs on. This stamp has all the correct attributes: 1866 cancel, distinctive thin green paper, almost translucent. Not to mention that the 3 expertizers listed on the 1991 PSE cert are noteworthy.
