USPS Numbered Postal Sheets of Pacific '97 Triangles, Scott Nos. 3130-31

I would not have liked that numbering job! However, the triangles made an attractive set.

I would leave the framing intact. Most likely it will retain the most value that way. The stamps came out a couple of months prior to the San Francisco World Stamp Expo named "Pacific 97". I believe New York City was where the first day ceremony was. I bought the uncut press sheet and parted it out into cross gutter pairs and other odd groupings similar to what people did years back with the Farley stamps. I seem to remember something about "numbered sheets" I can't tell you whether they were ordered out of the Philatelic Fulfilment cave or were available at the first day ceremony. I couldn't find anything online about them. The stamps are pretty common, even the press sheet is inexpensive. Most of the comments about them online seem to reflect the common theme about modern issues selling at face or below face value. I don't think the numbering adds anything significant to the value of the sheet, but obviously the framing does.

 

My best recommendation would be to see if you can find old Linn's Stamps News concurrent with the period. I was a former subscriber and am pretty sure that it was covered in the paper. I'm fairly certain that is where I read about it. Good luck on the mystery JCG.
