The Only BEP Perf. 11 Coil Stamp

Most Bureau of Engraving and Printing (BEP) coil stamps were made by the rotary press and were perforated 10 perforations per 2 cm. There are also other BEP coil stamps and they that were flat plate printed and they were perforated 12, 8.5 and 10. There is also only one BEP coil stamp that is flat plate printed and perforated 11. What is it? Hint: It can be found somewhere within Scott's U.S. Specialized Catalog.

For some reason, I'm thinking that Scott 461 may apply here. It is a flat plate, perf 11, but the interesting thing is that the paper shelvage states "Coil Stamps". I'll keep looking, but that's my first guess.

You may have to go into U.S. Possessions to find it.

OK, I was bored and in-between soccer games. I looked in Philippines and found Scott 326 which fits your description of BEP, Coil Perf 11 - Vertically. Whew ...

Yes, you are correct. This is the only BEP printed and perforated 11 vertically coil stamp. It is also the last flat plate printed BEP coil stamp since by 1928 all other coils were printed by rotary press. As a result, this coil stamp is found with paste ups. Thus, for those who collect U.S. coil stamps, this may be an interesting U.S. related BEP coil stamp that is different.
