This is a quite common occurrence due to the type of press used in the printing process.
Interestingly, I did note the partial vertical line at the bottom of the perforations on your example, so I went to the interent and came up with this quote to explain it:
Quote:
"Some coil stamps shows partial lines of ink along the perforations. It looks like it should be a line pair. However, the Scott catalog doesn't list prices for line pairs on these coil issues. That's because these stamps were printed on the Huck press. Unlike other rotary press coil stamps which have a gap between the printing plates yielding joint line pairs, the colored lines of ink on the Huck press printed stamps are not from a gap in the printing plates. These extra lines of ink are very common and have no extra value."
